Arms Mastery gives Phys Amp and +25% Accuracy when maxed.
Titanomachia at 6 MP, in Red, is an efficient AOE with high crit rate; transfer him a Crit Rate passive boost like Savage Glee or Epitome of Carnage for the AOE to be a devastating Crit machine.
Drain Phys and strong offense: decent candidate for Drain Teams.
Panels give him Phys Pierce, increase his defense and offense.
Cons
Heavily reliant on panels; without Panel 2, he needs Phys Pierce (weak) transferred and even then would be worth at best 5 in PvP rating.
No unique attack makes him Mid Tier in offensive ability.
