[Inaros] build for Arbitration
This cost a lot of platinum :c

[Swift Momentum] for +6s Melee Combo Duration.
Build for Melee playing. [Gram] | [Plague Keewar], or [Arca Titron].
You can stay alive for 120 mins on Arbitration. Bigger i can not stay because of teammates playing Garuda or Wisp, and we leaving always on 90-120. I think he can stay about 2 or 2.30 hours.

You can change Arcane Grace to Arcane [Guardian] + Arcane Victory.
little bit regeneration. But all will be okay by killing a lot of mobs.
