Living Death (Ex)
A lichling uses her casting ability modifier in place of her Constitution modifier when determining the number of hit points gained from her lichling levels. She may also use her casting ability modifier in place of her Constitution modifier when calculating her Fortitude saving throw.
This replaces channel energy.
Touch of Corruption (Su)
Beginning at 2nd level, a lichling may touch a target and fill it with negative energy. Each day she can use this ability a number of times equal to 1/2 her lichling level + her casting ability modifier. Using this ability is a standard action that does not provoke an attack of opportunity, but may be used on herself as a swift action. The lichling must make a touch attack against an unwilling target. If successful, this ability deals 1d6 points of damage per 2 lichling levels to the target. If used on an undead target, this instead heals the undead 1d6 hit points per 2 lichling levels. This ability is modified by any feat, spell, or effect that specifically works with the lay on hands paladin class feature. A lichling may spend a feat to gain an antipaladin cruelty, using her lichling level as her effective antipaladin level for this purpose.
The lichling may also channel negative energy as a cleric by spending 2 uses of her touch of corruption. The lichling uses her lichling level as her effective cleric level when channeling negative energy. This ability is based on casting ability.
This replaces blessing/blight.
Negative Energy Affinity (Ex)
At 6th level, the lichling is healed by negative energy and harmed by positive energy, as if she were undead.
Undead Resistances
At 10th level, the lichling gains a +2 bonus to all saving throws vs. death effects, mind-altering effects, energy drain, disease, paralysis, poison, and sleep. These bonuses increase to +4 at 14th level, and +6 at 18th level.
True Undeath (Ex)
At 20th level, a lichling ceases to age (becoming effectively immortal), and gains immunity to age effects, bleed effects, nonlethal damage, ability drain, and energy drain. Unintelligent undead ignore the lichling, treating her as one of their own unless attacked.
