IMHO, I think this is another case of an overpowered fanmade servant.

Pros: Cons:
 * High NP gain with his passive, first skill and the overcharge effect on his NP.
 * Really high stargen, exceeding even Gilgamesh's 7.9%, and we all know how much star Gil can generate even with only one Quick card
 * Can highly charge party's NP gauge, heal, and increases party's debuff removal resist by 100%  for 1 time (essentially making them immune to buff removal).
 * Buffs party with high +30% NP DMG for 1 time (possibly lasts indefinitely), and reduces enemy defense by 30% for 3 turns.
 * Can buff an ally's Buster performance by 40%, increases their damage by flat 3000 (both for 3 turns), and remove one enemy's buffs.
 * All skills have a really low cooldown for their effects.
 * Reduces enemy's defense from 20% to 40% for 3 turns, reduces their attacks for 50% for 2 turns (essentially becoming a better Asterios at this point), and seals their skills and NP for 1 turn, plus charges party's NP gauge depending on overcharge.
 * Pretty much nothing? He can do what Merlin mostly do (heals party) and Waver too (protecting party by debuffing enemy attack massively), and the ATK debuff only lasting 2 turns is theoretically negated with his high NP gain.

I'd say reduce the buffs and debuffs effect (such as his third skill's flat damage up from 3000 to just 1000) and increase the cooldown from 5/5/6 to 6/6/6 or 6/6/7.
