Arcane Barrier

Feats

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 (up to a maximum of 3). The temporary hit points from this ability don't stack with themselves, but additional uses do cause the total number of temporary hit points and the duration to reset.
