Pool Strike, Arcing
Benefit: The magus can expend 1 additional point from his arcane pool when using the pool strike arcana. If his attack hits, the magus can target a number of enemies within 15 feet equal to his Intelligence modifier (minimum 0) with a ranged touch attack as a free action. Those struck take the same energy damage as the primary target of the pool strike, including increased damage on a critical hit.
" Supernatural abilities are magical and go away in an antimagic field but are not subject to spell resistance, counterspells, or to being dispelled by dispel magic. Using a supernatural ability is a standard action unless noted otherwise. Supernatural abilities may have a use limit or be usable at will, just like spell-like abilities. However, supernatural abilities do not provoke attacks of opportunity and never require Concentration checks.
