Arcanist archetype

Twilight Sage

The twilight sages of Geb carry out experiments to solve the ultimate puzzle and unlock the secrets of life and death. While the twilight sages generally aren’t actively malicious, most are willing to perform human experimentation in pursuit of knowledge with little regard for the casualties.

Consume Life (Su)

Replaces Consume Spells.

By wresting a soul from life to death, a twilight sage gains a slightly deeper understanding of mortality, fueling her curiosity and eldritch power. As a full-round action, she can consume the life energy of a helpless living creature, killing it.

This creature must have 2 or more Hit Dice and be below 0 hit points. The twilight sage adds 2 points to her arcane reservoir if the creature’s Hit Dice equaled or exceeded the sage’s character level, or 1 point if the creature’s Hit Dice equaled at least 1/2 her character level. This ability is a death effect. This ability replaces consume spells.

Necromantic Focus (Ex)

Twilight sages consider their research into life and death to be paramount, beyond all other concerns. Each day, a twilight sage must prepare at least one necromancy spell of each spell level she can cast.
