Once the Mad Hound armor, this set has been enhanced by the power of Stygian Steel, reaching new limits.  This dark ninja like armor, practically oozing with raw wrath so palpable it can be felt by those around you, now grants the fury and wrath of the raging beast it was destined to be.

Genjutsu Mastery:  You become a master of the illusionary arts and may cast minor image at will.  When engaging in flighting, you may use a bonus action to make two additional copies of yourself that can do physical damage by substituting any extra attacks with them, move on your turn, and have spells originate from one of those clones while the others project a copy of the spell that does no harm.  Opponents can make an Investigation check vs your Deception to determine which one is the fake.
