Allied Spellcaster (Feat)

With the aid of an ally, you are skilled at piercing the protections of other creatures with your spells.

Prerequisites: Caster Level 11

Benefit: Whenever you are in an encounter with an ally who also has this feat, you automatically succeed on caster checks to overcome enemy creatures' spell resistance, as long as that creature's CR is no greater than your character level + 1 per ally who also has this feat.

Special: If you are adjacent to an ally who also has this feat, you also gain a +2 circumstance bonus on any caster checks you perform to cast defensively.

Note: This is a Teamwork Feat, meaning it does nothing unless you and at least one other member of your party each possess this feat.
