I am very fond of Item Mastery Feats for the Pathfinder Roleplaying Game. I think there are lots of interesting places those feats can take characters, especially fighters. I am also a big fan of the Advanced Weapon Training rules that allow fighters to make weapon training do more than just grant flat attack and damage bonuses. The two already combine somewhat (with the item mastery advanced weapon training option), but I think there are yet more interesting ways they can be mixed for fighters, and some other classes.
Arcane Fighter (Combat)
You know magic is a potent weapon, and you study how to fight with magic items.
Prerequisite: Fighter level 1.
Benefit: You are considered trained with Use Magic Device, and can make special UMD checks with a bonus equal to your fighter level + your Constitution bonus +3, rather than your normal skill bonus.
When you drink a magic potion, you gain additional benefits.
Prerequisites: One of the following class features: armor training, brew potion, weapon training.
Benefit: Select three item mastery feats for which you meet the prerequisites. Each time you gain a new level, you can change this selection.
Once per day when you drink a potion, you may use the benefit of one of those item mastery feats if the potion would qualify to grant you if it were a permanent magic item. You may use this feat a second time per day when your base attack bonus, caster level, or alchemist level reaches +5 or 5th, and every +5 or 5 levels thereafter.
Extra Weapon Training (Combat)
You are a master of many weapons and weapon fighting techniques.
Prerequisites: Weapon training class feature.
Benefit: You can select another weapon group your weapon training class feature applies its benefits to. Alternatively, you may select another advanced weapon training option for which you meet the prerequisites.
The point of the Advanced Item Mastery Training Feats article was to create new ways to use existing Item Mastery Feats and find synergy with advanced weapon training, rather than to present new Item Mastery Feats. However while writing it I thought of one new Item Mastery Feat which fills a gap in what those feats can allow a character to do: Buff Mastery. It is presented at my Patreon, exclusively (for now) for my Patrons!
