(7.7a) Polymorph rings ('Ring of Polymorphing of <form>'):
(7.7) Mimicry details                                                           
---------------------
If a mimicry-user polymorphs into a certain monster form, stats and some
abilities will be averaged between the normal ('@') body and the form. In most
cases if the form is performing worse than @-form in a certain field, the '@'
form (ie the normal 'player' form) will dominate and the ability will be only
slightly worse than normal, if even at all.
The averaging is done because the mimic with all his equipment polymorphs into
the target form. It's not like the polymorphing is done first and afterwards
armour, weapon or jewelry is equipped.
So wearing a ring of protection for example won't plainly add to the mimic's
AC but just contribute to the @-form AC which is then averaged in the process
of determining the final form's AC.
How exactly stats are calculated is written below for each case.

If a mimic wields a weapon while using a form which usually cannot use weapons
the number of blows per round will be set to 1 (regardless of extra attacks).
(This only really applies to druids, shamans or perma-cursed weapons (5.12)).

If a mimic polymorphs into a form that cannot wear certain pieces of equipment,
these will all be taken off and placed into the inventory in the usual sorting
order, possibly overflowing your pack if there is not enough room, dropping the
bottom-most item from it to the floor for each item too many. An exception are
perma-cursed items, which can never be removed except by death.

Apart from blows-per-round, all the other resistances and abilities of a
perma-cursed item will be applied normally though, so you could wear the
Massive Iron Crown of Morgoth to get all the resistances and ESP with a form
that usually cannot wear any head gear.

To find out the special abilities of a monster form, press  ~ 7  in game or
consult a spoiler file. (See (8.4) for more info about spoiler files.)
You can also use Mikael's monster search website under ~R .
It's abilities will transform to the mimic's body as follows.

Very useful for searching for monster forms with specific abilities is
Mikael's monster search website, linked on tomenet.eu and invokable in-game via
~ R  (Shift+R in the 'Knowledge' menu, this requires at least client 4.7.3).


Form aspects as specified in  ~ 7  monster lore:
(Make sure to keep your r_info.txt spoiler file up to date, as the lore
displayed via ~7 is derived from it.)
-----------------------------------------------------------------------
W: depth : rarity : corpse weight : experience for kill
  depth:
    The depth is also the basic level of these monsters. It tells you how
    many of them you need to kill to learn mimicking their form.
    The level has additional use for calculating the mimic's final hit points
    regarding very high character levels (see 'hit points' below).
  corpse weight:
    The weight of the form has impact on its stealth. A huge form that weighs
    a lot will give a stealth penalty, while small and light forms may give a
    bonus.
    Also, the mimic will burn food faster while mimicking a heavier monster.

I: speed : hit points : vision : armor class : alertness
  speed:
    110 means normal speed. If the monster is faster, the mimic will
    receive a speed bonus of 30% of the monster's speed above 110.
    If the monster is slower, the mimic will receive a speed malus of
    20% of the monster's speed malus below 110.
    So a monster moving at 130 speed will give the mimic +6 speed.
  hit points:
    The monster's hit dice xdy are multiplied and then somewhat capped against
    ~2500, so HP gain might decrease in higher regions. (Cap details: The
    monster HP is calculated by the following formula before further
    calculations are made: monster HP = 50000 / ((50000 / hdice*hsides) + 20).)
    Now, if the mimic's HP are less then the result, the mimic's HP will
    become approx. 2/5 of that capped monster HP + 3/5 of the player's original
    HP. If the mimic's HP in player form (code 0) are higher than the monster
    HP then the monster HP will not have any adverse effect, instead the normal
    HP will stay.
    A specialty: Players in very high character levels can see their hit points
    'overtake' the monster form hit points, if the monster form level isn't
    very high in comparison. Example: While a green dragonrider will provide a
    great HP boost, if the player himself has reached say level 70 and has lots
    of HP even in normal form, the green DR hit points won't add much anymore.
    If however the monster has high hit points and also a very high level, the
    monster HP will 'stay ahead' of the player hit points ie keep adding a
    steady bonus that will put him well ahead of his player-form hit points.
    So players of very high character level who want to retain a large bonus of
    hit points will want to look for forms of monsters which are also of
    relatively high level.
  armour class:
    Mimicking a monster is already a very difficult task. By changing
    shape, the usual armour class of the monster will magically influence
    the armour class of the player.
    Depending on the body parts of the monster, its AC has different
    influence on the player. The following formula helps:
    body_influence = 0.
    if the monster has a head, body_influence is increased by 1.
    if the monster has a torso, body_influence is increased by 3.
    if the monster has arms, body_influence is increased by 2.
    if the monster has legs, body_influence is increased by 1.
    calc_ac = monster_AC * 14 / (7 + body_influence)
    Now if calc_ac is smaller than the player's AC, the final AC will be
    (3/4 player_base_AC) + (3/4 player_magical_to_AC) + (1/4 calc_ac).
    Otherwise, the final AC will be
    (1/2 player_base_AC) + (1/2 player_magical_to_AC) + (1/2 calc_ac).
  vision:
    Searching ability of the player =
    (player_searching / 2) + (monster_vision / 10)
    Perception of the player =
    (player_perception / 2) + (monster_vision / 10)

E: hands : torso : arms : finger : head : leg
    These values indicate how many pieces of equipment the player can
    wear while using this form. For example snakes can only wear a helmet
    (E:0:0:0:0:1:0).
    NOTE: Mimics can never wear MORE items than in their normal form. So
    even a form with 8 legs would allow only 1 pair of boots to be equipped!
    In the monster lore (~7) some monsters may show 'tentacles'. These count
    for three limb-types together: Hands regarding wielding a weapon, fingers
    (can wear rings) and arms (can wield shields). Tentacles are not fit for
    wearing gloves though.

B: attack method : attack effect : damage
  attack effect:
    POISON,DISEASE,FIRE,COLD,ELEC,ACID:
      If the monster poisons or infects with disease, this will result in
      a poison brand. Similar it's for fire/cold/lightning/acid attacks.
    BLIND won't work on monsters that have NO_SLEEP, otherwise the target
      will be confused.
    HALLU and CONFUSE won't work on monsters that have NO_CONF,
      otherwise the target will be confused.
    TERRIFY won't work on monsters that have NO_FEAR, otherwise it'll
      scare the target.
    PARALYZE won't work on monsters that have NO_STUN, otherwise it'll
      stun the target.
    EXP_xx means the monster drains life on attacking. The player will
      receive HOLD_LIFE (resist life-draining attacks) from this form.
      (It doesn't matter how strong the attack is, all of the variations,
      EXP_10, EXP_20, EXP_40, EXP_80, have the same effect.)
    SHATTER will result in a bonus to player's STRength attribute.
    LOSE_xxx will give the according sustenance, or even all sustenances for
      LOSE_ALL. All other variations give single sustenance each:
      LOSE_STR, LOSE_INT, LOSE_WIS, LOSE_DEX, LOSE_CON, LOSE_CHR.
    SEDUCE will grant charisma sustenance.

    Monster effects (like poisoning or paralyzing) are applied to
    the player's attacks with a probability that corresponds to their
    rarity over the up to 4 monster attacks per round.
    Example for 'Ghoul' form:
    If the monster has 3 blows per round and one of them is poisoning,
    the other two are paralyzing, the mimic will have 1/3 chance to do
    a poison branded attack and 2/3 chance to do a stunning attack.

    These effects won't be applied if one of the following conditions
    is met:
    a) The player is doing a ranged attack.
       (Effects only work with melee attacks!)
    b) The player uses a weapon but the monster doesn't have an
       equipment slot for melee weapons, because it has no arms or is
       immaterial.

    Melee to-damage bonus also depends on the monster form:
    The monster damage dice for each attack are multiplied and the products
    are all added up, the result is divided by 4.
    The result is now capped against 200, the closer this graph comes towards
    200 the flatter the curve will become. Let's call the resulting monster
    damage value 'monDam':
    This value is now compared against the player's melee to-damage bonus.
    If (monDam > meleetoDam) then newToDam = 1/2 meleetoDam + 1/2 monDam.
    If (monDam < meleetoDam) then newToDam = meleetoDam.
    So, very similar to how HP are averaged, the monster damage has no
    influence if it's lower than the player's melee to-damage bonus, but it
    may provide a great boost if the monster is more powerful than the player.

F: flag list
    The flags are translated to mimic abilities as follows:
    RES_xxx     Gives the mimic the specific resistance.
    IM_xxx      Gives the mimic the specific immunity! If a form offers
                more than 1 immunity, the immunities will be checked against
                the preferences you set, if none match or if you set it to none
                then one will be picked randomly. The remaining ones will turn
                into resistances. Potions of self-knowledge are helpful here to
                find out which one you got, or you could just suffer damage of
                the according type on purpose to test it out.
                You can set the desired immunity in 'm' menu ->
                'Use innate power' -> 'Set preferred immunity'. It will be
                picked if the form you polymorph into can provide it.
                If you are already using a form that can provide the immunity
                that you switch to, that immunity will become the active one
                immediately without the need for re-polymorphing.
                Note that two immunities are actually exempt and don't
                translate directly:
                    IM_TELE gives teleport resistance (like RES_TELE) instead.
                    IM_PSI gives insanity reduction (like EMPTY_MIND) instead.
    PASS_WALL   Will allow the mimic to pass walls like a ghost.
                These immaterial forms also drain the hit points of their
                user.
    KILL_WALL   The mimic will dig *easily* through walls.
    REGENERATE  Faster hit point regeneration (same as item ability, doesn't
                stack with regeneration obtained from item flag).
    REFLECTING  Gives 'REFLECT' passive ability to the player, see (5.8).
                Also gives resistance to light.
                (Side note about monster reflection in general:
                The 'REFLECTING' flag on monsters gives them a flat 50% chance
                to reflect physical or magical projectiles and resistance to
                any light-based attacks.)
    CAN_SWIM    The player can swim in water, provided he isn't carrying too
                many/heavy items.
    CAN_FLY     The player can levitate.
    STUPID      -2 intelligence.
    SMART       +2 intelligence.
    NO_CONF     Confusion resistance.
    NO_FEAR     Fear resistance.
    NO_SLEEP    Free action.
    NO_STUN     Sound resistance.
    NO_CUT      The player can't be cut and won't bleed continously from
                wounds.
                This will also render the player immune against cause wounds
                ("Monster points at you and curses/incanting terribly/screaming
                the word 'DIE'").
    DISBELIEVE  Will provide (or increase an already existing) anti-magic field
                by ((monsterlevel / 2) + 10) percent. The range of the field
                is set to (or increased by) ((monsterlevel / 50) + 2) fields.
                The usual limits of the Anti-Magic skill apply, see (7.2) for
                details.
    ARROW_1, ARROW_2, ARROW_3
                The player will receive an extra shot per round with slings or
                bows since the monster seems to be good at shooting.
                If the monster shoots 1_IN_3 or better (better means faster,
                ie higher frequency, that is 1_IN_2 or 1_IN_1), the player will
                receive an additional extra shot (with crossbows too).
    HURT_ROCK   Means that this creature has a rock-like skin and body.
                Takes damage from Stone-To-Mud and takes more damage from
                'disintegration' attacks, but at the same time resists shards!
    WILD_WOOD   The player (like the monster) can pass trees.
    WILD_MOUNTAIN or WILD_VOLCANO
                The player (like the monster) can climb mountains.
    WILD_TOO without any other WILD_xxx flags:
                Combines all WILD_xxx effects (such as WILD_WOOD and
                WILD_MOUNTAIN)!
    INVISIBLE   The player becomes invisible (see (5.14) for details).
    AURA_FIRE or AURA_ELEC
                The player receives an aura.
    SUSCEP_FIRE/SUSCEP_COLD/SUSCEP_ELEC/SUSCEP_ACID/SUSCEP_POIS
                The player is susceptible against these attacks. Dangerous!
    WIERD_MIND/RES_PSI
                Insanity attacks are reduced a little bit. See (7.6).
    EMPTY_MIND/IM_PSI
                Insanity attacks are reduced somewhat. See (7.6).
    AQUATIC     Cuts down damage from water-based attacks against you to 1/4,
                overriding 'normal' water resistance (if you have it).
                Prevents your items from getting harmed by water in any way and
                completely prevents stun and confusion effects from water-based
                attacks.
                Allows you to swim freely and at maximum running speed.
                However, since you cannot breathe air in aquatic form, you will
                suffer from Anoxia and can get stunned and even die from it if
                you aren't in deep water, or - if your mimicked form weighs at
                most 700 lbs - in shallow water. You are also safe from this
                effect if your mimicked form is actually UNDEAD or while you
                are in wraithform.
    NEVER_MOVE  Using this form, the player won't be able to move (except for
                teleportation/phasing/recalling).
    RAND_25     The player has +10% chance of moving randomly.
    RAND_50     The player has +20% chance of moving randomly.
    OPEN_DOOR   This form can open doors.
                Note that forms can open doors even if they don't have this
                flag, provided they have fingers and are able to wield weapons
                (a good example are Minotaur/Maulotaur forms of druids).
    BASH_DOOR   This form can bash doors
                (useful to forms that cannot open doors, see OPEN_DOOR flag).
    HURT_LITE   This form will take 2x damage from light attacks.
    HAS_LITE    If this monster either doesn't have a torso or can actually
                breathe light, it will give you +1 light radius.
    POWERFUL    Gain +1 radius when using monster's ball or breath attacks.

    For all racial flags such as ANIMAL, SPIDER, EVIL, DEMON etc please see the
    list of racial abilities further below.

S: spell list
    These spells can be cast by the monster. Most of them are available to
    the mimic too, called 'mimic powers', some of them may have slightly
    different effects when used by the mimic. For a list of all available
    mimic powers see (7.8a).
    The chance to successfully use such a monster power is affected by the
    mimic's intelligence (INT).
    Depending on how frequently the monster is able to cast spells, the player
    gets boni on mana and on intelligence or wisdom stat!
    This only applies if the spells are in fact magic spells, not if the
    monster cannot do anything except firing missiles, shrieking or shooting
    arrows (etc).
    If the creature is able to cast 1_IN_3, the player receives +1 stat and
    +20% Mana bonus (of base mana, same way +MANA items work).
    If the creature is able to cast 1_IN_2, the player receives +3 stat and
    +35% Mana bonus (of base mana, same way +MANA items work).
    If the creature is able to cast 1_IN_1, the player receives +4 stat and
    +50% Mana bonus (of base mana, same way +MANA items work).

    About specific spells:
    BR_xxx      (breathing) will give the according resistance to the player
                (if that specific attack CAN be resisted at all).
    BR_PLASMA   gives fire immunity and resistance to electricity and sound.
    BR_GRAVITY  gives feather falling.
    BR_INERTIA  gives free action.
    MIND_BLAST  Insanity attacks are reduced a little bit. See (7.6).
    BRAIN_SMASH Insanity attacks are reduced somewhat. See (7.6).
    The mana costs of mimic powers are fixed, the success chance is relatively
    fixed too although it benefits somewhat from 'Magic' skill.

Especially interesting spells of mimics are 'Blink' (Phase Door) and
'Teleport'. These usually cost very little mana and can be very helpful,
so you might want to create macros for them.

                for example quaffing lots of healing potions quickly.
                Take 2x damage from holy orbs or holy fire and suffer

All greater demons (capital 'U')
                See 'All demons' above, and in addition they
                resist poison (usually immunity, depends on ~7 flags), time
                and chaos.
All non-living creatures
                Resist poison (usually even immune, depends on ~7 flags)

                Vampire bats and mist have 100% chance to do a vampiric attack,
                real vampire forms (and vampiric ixitxachitl) have 50% chance
                (half their attacks are hits, the other half is biting).
                For details see '(5.13) Vampirism'.
All angels      Resist light, blindness and poison (usually immunity, see ~7
                flags), resist fear, resist confusion, free action, some
                resistance to insanity-inducing attacks (see (7.6)), see
                invisible.
                Note: 'Fallen Angel' doesn't get light resistances.
Mist and fume   Feather falling.
All cold-immunes
                Do not slip, but walk steadily on icy floor.

Keep in mind that by changing forms you can potentially lose abilities that
you had in player form, because they were bound to your normal form.
Example: An ent mimic won't drown in water, but if it polymorphs into an orc,
it loses the intrinsic ability to swim in water since orcs aren't made of wood.


Attributes and miscellaneous abilities can also be affected by certain aspects
of the monster form you use:

Intrinsic abilities that aren't kept when changing forms:
---------------------------------------------------------
Characters keep certain racial abilities even if they change form, while some
other abilities might not persist through polymorphing. The following abilities
will NOT remain active when changing shape, ie are not "polymorph-proof":

Hobbit:
    +DEX bonus from not wearing shoes.
Dwarf:
    Climbing.
Yeek:
    Pass trees.
Ent:
    Speed malus (will be reduced), swimming, pass trees.
    (Note that Ents KEEP racial water resistance and fire susceptibilitiy.)
Draconian:
    Feather falling, levitation.
    Intrinsic breath weapon - you can only use it if you're actually in dragon
    form (including dragonriders) or in any reptilian form (including Hydras).

Abilities acquired from traits (such as 'enlightened' or 'corrupted' trait for
Maiar or draconian traits) are also considered intrinsic abilities and
therefore polymorph-proof if they aren't on the list above.
