Long ago me and a pal (ORSMurgoo) took some free time to imagine an eddie for this pic.
This is the result: a 4* star assassin eddie (the game has no one), which role should be more tanky support, with some buffs and debuffs. Highlights are in permadeth (should be usable in pvp) and a new take on Ghost buff (now a high risk high reward revive).
