Consume Life (Su): 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.
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.
Arcane Barrier (Su): As a swift action, the arcanist can expend 1 point from her arcane reservoir to create a barrier of magic that protects her from harm. This barrier grants the arcanist a number of temporary hit points equal to her arcanist level + her Charisma modifier, and lasts for 1 minute per arcanist level or until all the temporary hit points have been lost. Each additional time per day the arcanist uses this ability, the number of arcane reservoir points she must spend to activate it increases by 1 (so the second time it is used, the arcanist must expend 2 points from her arcane reservoir, 3 points for the third time, and so on). The temporary hit points from this ability do not stack with themselves, but additional uses do cause the total number of temporary hit points and the duration to reset.
Twilight Barrier (Ex): A twilight sage's arcane barrier differs from those of other arcanists, as it draws upon both negative and positive energy to protect the sage. At 1st level, a twilight sage must choose the arcane barrier exploit as her first arcanist exploit. Whenever an attack removes the last temporary hit point from the twilight sage's arcane barrier, the barrier's negative energy lashes back at the attacker, dealing an amount of negative energy damage equal to the barrier's maximum temporary hit point capacity.
