Technically the 30% damage/30% burst is Typhon, not Yata. But that's just me being a dick.

The eidolon itself doesn't look impressive at all. The bonuses are meh, stats are low (678 HP/1464 ATK at max level), and a DoT debuff isn't what I'd call game-changing. Not a substantial improvement over Garuda as a main water eido, and not very useful as a sub either.

I'll take the weapons, though. My water grid is just pathetic...
