The arcanist can temporarily disrupt a spell by expending 1 point from her arcane reservoir and succeeding at a dispel check against the spell, asdispel magic. This ability suppresses a spell effect for a number of rounds equal to the arcanist’s Charisma modifier (minimum 1). If the spell affects multiple creatures, this ability only suppresses the spell for one creature. At the end of this duration, the spell resumes and the suppressed rounds do not count against its total duration. This ability can be used on unwilling targets, but the arcanist must succeed at a melee touch attack, and the target may attempt a Will saving throw to negate the effect. This ability has no effect on spells that are instantaneous or have a duration of permanent.
