Crescent Cross Training

FEAT 4

You have familiarity with the Crescent Cross, an ingenious weapon that combines an arm-mounted, multi-chamber crossbow with a crescent-shaped blade. For the purposes of proficiency, you treat both its configurations as simple weapons.

Feats and abilities from this archetype that normally work with a gauntlet bow also work with your crescent cross, treating the melee form of the crescent cross as a gauntlet where appropriate. You gain the Crescent Spray action.
