Ferrous Emissary
The magic that fuels a ferrous emissary’s arsenal takes on a distinct personality, manifesting its own will in the form of a sentient weapon.
Sentient Weapon (Su)
At 1st level, one of the ferrous emissary’s bound equipment becomes a powerful, sentient black blade. The blade advances as per a bladebound magus’ black blade class feature, using the ferrous emissary’s class level in place of the magus’ class level and spell points in place of the magus’ arcane pool (this does not reduce the ferrous emissary’s pool of spell points). The sentient weapon uses the enhancement bonus progression of bound equipment rather than the progression of a normal black blade, and gains its own arcane pool as normal. When targeting only the black blade with an effect that requires spell points, the ferrous emissary may spend the black blade’s arcane pool points in place of spell points.
The ferrous emissary may exchange her bound weapon for another piece of bound equipment, with the consciousness of the sentient weapon transferring to the new piece of bound equipment. The consciousness of the sentient weapon can even inhabit implements or armor, transferring the effects of black blade strike, energy attunement, and life drinker to a single weapon the ferrous emissary is wielding.
This ability alters bound equipment
Weapon Training (Ex)
At 5th level, the ferrous emissary gains a +1 bonus on weapon attack and damage rolls with all weapons from a single fighter weapon training group of his choice. This bonus increases by +1 at 9th level and every four levels thereafter. This counts as, and does not stack with, the fighter’s weapon training class feature.
The ferrous emissary can select advanced weapon training options in place of armorist tricks. They may only select such abilities once for every 4 armorist levels they possess.
This replaces the additional piece of bound equipment gained at 5th level. At 10th, 15th, and 20th levels, the armorist can choose between gaining a piece of bound equipment and gaining weapon training with another fighter weapon training group.
