Hope you like this Pathfinder RPG feat, designed for the Magus class.
Your mastery of technique lets you convert martial skill into magical penetration.
Prerequisites: Improved spell combat class ability, Int 15, Dex 15
Benefit: When you roll both an attack roll with a weapon and use a spell in a full attack, you can choose to use your attack result as your caster level check to overcome spell resistance. Negate any results of your weapon attack if you do so.
This feat is intended to give certain maguses an interesting option. It’s possible to end up in a situation where a combat-focused magus can’t get any spells through because they’re facing a lot of enemies with high spell resistance (like, say, a demon horde) and they don’t have the necessary feats or build to overcome the SR. With this feat, that combat-focused magus can choose to push a spell through the SR when necessary, at the cost of their weapon damage.
