Weapon: Wizard Rod ATK 18, MAG 72 (Chamber of the Fallen: Surging Menace) Shield: None Hat: Circlet DEF 10 MAG 15 SPR 7 (Wind Shrine - Exploration) Body: Black Robe DEF 34 MAG 20 (Ghost Ship - Exploration) Accessory 1: Earring DEF 3 MAG +20% (Fat Chocobo) Accessory 2: Earring DEF 3 MAG +20% (Fat Chocobo) Materia Slot 1: MAG +10% (Silver Chest) Maranda Coast - Exploration Materia Slot 2: MAG +10% (Silver Chest) Maranda Coast - Exploration Materia Slot 3: MAG +10% (Silver Chest) Maranda Coast - Exploration Materia Slot 4: MAG +10% (Silver Chest) Maranda Coast - Exploration Esper: Diabolos This build allows arc to get a very significant amount of MAG (351) for a 5 star unit without TMR allowing his dual black magic skill to wipe the board quite easily. I prefer Diabolos over Ramah since Arc already gets Osmose and this esper unlocks death / biora / drain. On weeks when it is permitted double casting biora in conjunction with a full party bio blaster allows for some fairly spectacular dark damage chains. Todo is upgrade the black robe to a magi robe, but ive been focusing on arena more than coliseum. Performance wise this arc will 1 shot on turn 1 the Myrmidon on Hanging Garden Pro doing a Firega amplification off a full party wall without debuffs. (PRO > ELT since you can basically stack all bonus heroes and have arc clean up the different stages, I have farmed about 120k trichoid gears using this method). I will probably get more mileage out of this setup with the exdeath I just got now that he is 6 star with dual black magic, but I have been using this Arc build for awhile so I figured I would share.
