Counterspell (Su)

Benefit(s): By expending 1 point from your arcane reservoir, you can attempt to counter a spell as it is being cast.

You must identify the spell being cast as normal. If you successfully do so, you can attempt to counter the spell as an immediate action and by expending an available arcanist spell slot of a level at least one higher than the level of the spell being cast.

To counterspell, you must attempt a dispel check as if using dispel magic. If the spell being countered is one that you have prepared, you can instead expend an available arcanist spell slot of the same level, and you receive a +5 bonus on the dispel check. Counterspelling in this way does not trigger any feats or other abilities that normally occur when a spellcaster successfully counters a spell.
