Illuga
Illuga doesn't do much damage himself, but he's the key that pushes Zibai and the whole Lunar-Crystallize team well above their normal ceiling — his EM buff scales directly with reaction damage. Favonius Lance or the craftable Kitain Cross Spear are plenty, no premium weapon needed. Prioritize Energy Recharge first so he can burst every rotation, then stack as much Elemental Mastery as possible through the Silken Moon's Serenade set. If you're not building a Crystallize team, Illuga is close to useless — don't waste resources on him.
