 actors.mobs.tormentedspirit.desc=Tormented spirits are otherwise good-natured spirits that have been afflicted by a curse. So long as they are cursed they will attack just like a wraith, and are more powerful as well!\n\nIt may be possible to cleanse the curse by using the right item while next to the spirit. If the curse is lifted the spirit will surely be grateful...

-actors.mobs.vaultrat.desc=This rat has some behaviour changes to test out new vault enemy AI:\n_-_ Its movement can be 'heard' through walls\n_-_ It will wander along a pre-set patrol\n_-_ While wandering it has sharply reduced detection chance behind the direction it moves in.\n_-_ When it detects you it will 'investigate' before swapping to hunting. Investigating enemies move toward you but don't attack and are easier to lose behind doors and corners.
