Force Strike (Su)
Source: Advanced Class Guide, p. 11
The arcanist can unleash a blast of force by expending 1 point from her arcane reservoir. This attack automatically strikes one target within 30 feet (as magic missile) and deals a number of points of force damage equal to 1d4 + 1 per arcanist level. Spells and effects that negate magic missile also negate this effect.
