This is actually a sleeper hit of a CE, I've found. It's great to put on your lynchpin servant in a boss fight. The -400 flat damage cut (as with all anytime0gacha 4* CEs, you'll inevitably LB this) is actually really significant, considering defense buffs are widespread. If not universal, due to Mash. Star Absorption is also a very useful passive, obviously.

A good fit for tankier servants. Any of the Rulers work well.
