Lich (pale master)

Driven by ambition, some powerful spellcasters attempt to cheat death itself. Those who succeed become Liches. Those who fail are cast into the Abyss.

Special abilities
A lich has damage reduction 15/+1 as well as 100% cold and electrical immunity. This creature also has most of the usual undead immunities, specifically to critical hits, disease, level drain, ability drain, mind-affecting spells, paralysis, poison, and sneak attacks. However, a lich does not have the usual undead immunity to death magic. (Probably a bug.) A lich has +4 turn resistance.

The attacks of a lich stun on-hit. In addition, this creature has use of a doom gaze thrice per day.

A lich is a level 19 wizard with the following spells prepared.
