Surplice Aquarius Camus was a Frost controller: he spread Ice Seals, added extra freeze stacks and protected a single ally with his coffin. Freeze was never enough to keep him relevant — outside teams built around Poseidon Seraphina, who already handles all the control, Frost units are nowhere in the meta — so Camus became a filler pick with weak damage and one panic shield.
His Repaired Cloth (RC) does not improve the freeze: it changes his job. The rebuilt skill is the one that defined him, and it now turns him into a full protector: he covers several allies in the same round, absorbs everything that reaches them before their turn, answers with a small counter-hit, heals for the damage taken and cleanses their debuffs. He can even protect himself once per battle, which makes him feel far tankier than his stats suggest.
That flips his place in the meta. He never spends Energy himself and does not even need a turn: he only asks his team to burn Energy so the coffins keep charging. Heavy consumers like Mephistopheles Yoma therefore cover the whole lineup by round two or three — and a slow lineup gives him nothing to work with. His Cosmos change just as much: Speed and Status HIT are gone, what he wants now is survivability.
However, he is still fairly easy to kill while no coffin is active, he cannot stop a team that gets wiped before the first one charges, and non-purifiable control, like Seraphina’s Sacred Ice, ignores his cleanse.
Is the RC worth it? Yes. He is cheap in Skill Books, the correct order now starts with his protection skill, and any account that already plays Energy-hungry units gains a support that turns lost games into very long ones. He is one of the best defenders in the game, a brutal defensive force under the right circunstances.
