A lich is an undead spellcaster, usually a wizard or sorcerer but sometimes a cleric or other spellcaster, who has used its magical powers to unnaturally extend its life. A lich is a gaunt and skeletal humanoid with withered flesh stretched tight across horribly visible bones. Its eyes have long ago been lost to decay, but bright pinpoints of crimson light burn on in the empty sockets. "Lich" is an acquired template that can be added to any humanoid creature (referred to hereafter as the base creature), provided it can create the required phylactery (see below). A lich has all the base creature's statistics and special abilities except as noted here.
A lich gains the following.
A lich gains a touch attack which it can use at the base creature's combat proficiency.
Touch (1d8+5 necrotic damage plus paralysis). Paralysis: Any living creature a lich hits with its touch attack must succeed on a Con save or be permanently paralyzed. Remove paralysis or any spell that can remove a curse can free the victim.
In a full-attack, the lich can use a primary weapon plus its touch attack with the off-hand. A lich retains all the base creature's special attacks and gains those described below. The lich also retains any natural weapons or weapon proficiencies it had in life.
A lich retains all the base creature's special qualities and gains those described below.
An integral part of becoming a lich is creating a magic phylactery in which the character stores its life force. As a rule, the only way to get rid of a lich for sure is to destroy its phylactery. Unless its phylactery is located and destroyed, a lich reappears 1d10 days after its apparent death.
Each lich must make its own phylactery, which requires the Craft Wondrous Item proficiency. The character must be able to cast spells and have a caster level of 11th or higher. The phylactery costs 120,000 gp to create.
The most common form of phylactery is a sealed metal box containing strips of parchment on which magical phrases have been transcribed. The box is Tiny and has 40 hit points, hardness 20, and a break DC of 40. Other forms of phylacteries can exist, such as rings, amulets, or similar items.
