At 1st level, an arcanist can expend an available arcanist spell slot as a move action, making it unavailable for the rest of the day, just as if she had used it to cast a spell. She can use this ability a number of times per day equal to her Charisma modifier (minimum 1). Doing this adds a number of points to her arcane reservoir equal to the level of the spell slot consumed. She cannot consume cantrips (0 level spells) in this way. Points gained in excess of the reservoir's maximum are lost.
