 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.tormentedspirit.thank_you=Thank you...
 
+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.

 actors.mobs.warlock.bolt_kill=The shadow bolt killed you...
 actors.mobs.warlock.desc=As the dwarves' interests shifted from engineering to arcane arts, warlocks came to power in the city. They started with elemental magic, but soon switched to demonology and necromancy. The strongest of these warlocks seized the throne of the dwarven city, and his cohorts were allowed to continue practising their dark magic, so long as they surrendered their free will to him.\n\nThese warlocks possess powerful disruptive magic, and are able to temporarily hinder the upgrade magic applied to your equipment. The more upgraded an item is, the more strongly it will be affected.
