Pathfinder 2e Action / Feat: Titan Mauler

Trigger You use the Rage action on your turn.

Description You can use a weapon built for a Large creature if you are Small or Medium (both normally and when raging). If you’re not Small or Medium, you can use s weapon built for a creature one size larger than you.
Applications You gain access to one weapon of those larger weapons, of any weapon type otherwise available at character creation. It has the normal Price and Bulk for a weapon of its size . When wielding such a weapon in combat, increase your additional damage from Rage from 2 to 6, but you have the clumsy 1 condition because of the weapon’s unwieldy size. You can’t remove this clumsy condition or ignore its penalties by any means while wielding the weapon.   If you have Weapon Specialization increase the damage from Rage when using a larger weapon from 6 to 10; if you have greater weapon specialization, increase it from 10 to 18.
