(General)
Creatures you summon can act as proxies to deliver your spells to foes.
Prerequisites
Ability to cast conjuration (summoning) spells or a conjuration (summoning) spell-like ability,
Caster Level 5th.
Benefit
Whenever you cast a touch spell while adjacent to a creature you summoned (including an eidolon), you can have the summoned creature carry the spell's
Charge. Once the spell is cast, you and any creature you summon gain the
Share Spells ability (Core Rulebook 52). This feat doesn't qualify you for feats or other rules options that require you to have an animal companion, familiar, or similar allied creature with the
Share Spells ability.
