Magical Onslaught
Feat 10
Source Pathfinder Impossible Magic
Your eidolon's attack provides you an opening for one of your spells. Your eidolon makes a melee Strike against a creature, and then you cast a 1- or 2-action cantrip targeting the same creature. If your eidolon's Strike hits, the creature is Off-Guard against your spell (if it requires a spell attack roll) or takes a –2 circumstance penalty to its save against your spell (if it requires a saving throw). If your eidolon's Strike and the spell deal the same type of damage, combine the damage of both for the purpose of resistances and weaknesses. Both your eidolon's attack and any spell attack roll you make count toward your multiple attack penalty, but the penalty doesn't increase until after both attacks have been made.

PolymorphThese effects completely transform the target into a new form. A target can't be under the effect of more than one polymorph at a time. If it comes under the effect of another, the second effect attempts to counteract the first. If it succeeds, it takes effect, and if it fails, the spell has no effect on that target. Any Strikes granted by a polymorph effect are magical. Unless otherwise stated, polymorph spells don't allow the target to take on the appearance of a specific individual creature. If you take on a battle form with a polymorph spell, the special statistics can be adjusted only by circumstance bonuses, status bonuses, and penalties. Unless otherwise noted, the battle form prevents you from casting spells, speaking, and using most manipulate actions that require hands. (If there's doubt about whether you can use an action, the GM decides.) Your gear is absorbed into you; the constant abilities of your gear still function, but you can't activate any items. You lose your Speeds and gain those of the battle form. If a polymorph effect causes you to increase in size, you must have space to expand into or the effect is disrupted.
