In version 1.4 it is now possible to come across lich-type monsters.
They are stronger versions of normal monsters but with added abilities and a phylactery. Liches will revive after a while if their phylactery is still around but they will viciously defend their phylacteries so it's a good idea to kill them first and go after the phylactery while they're still dead.
They give triple the xp of their normal counterparts and killing the phylactery will uncurse anything you have equipped. They are generally non-aggressive though so it's up to you if you want to fight them.
Also added in this update is
auto-slowdown when you bump into a monster while holding shift
ROGUE-FP is a blend of old school classic roguelike gameplay with new school first person controls and perspective. There is no movement grid and no rigid turn system to slow you down.
Synopsis
The Fighters guild has a high bar for entry. They want you to delve deep into the Dungeon of Doom and return to the surface with the Amulet of Yendor. A perilous quest few have completed, for within the dungeon are terrible monsters, devious traps, and mystifying magical items. To survive you'll have to identify the items, navigate the dark labyrinths within the dungeon, and fight your way past the monsters. With enough skill and a decent amount of luck they say it can be done. Give it your best shot!
