Do you like when your books/scrolls/whatever gets destroyed by monster's attacks or trap. It could be hard to survive when you lose one of your essential spells and you do not realize immediately.
Example: Losing disruption shield scroll when it's still on. You do not cast it all the time but when you cant recast it you may die.
Big colorful message can save life. You still may be able to teleport away and recall. But you have to know that you're in danger.
Sound can be an additional option or alarm can be configurable.
I dont have better ideas for how it may look like yet.
ALARM - default message + sound
alarM - just message
alarmS - just sound
Alarm should be triggered when item is destroyed, dropped or taken off (we love sirens and other womanlike mobs )
