Considering summons (Sorcerer and Necromancer) attack scale off MATK, would Thaumaturge swell left arm, the ability that increases yours and the parties PATK and MATK, increase the damage of sorcerer and necromancer summons? I might be mistaken though, do they scale from our weapons MATK and not overall MATK?
This would be a full SPR build, Swell Left Arm scales from SPR as well as INT?
