wtf is a black grail

you know what maybe i'm better off not knowing

It's a 5* Craft Essence which is essentially the best one in the game. It massively increases NP damage at the trivial cost of 500 damage to the Servant equipped with it per turn. It also has a higher ATK value than most other CEs. And Oberon's S3 applies to it as well - doubling its already massive effect.

Basically the only other Craft Essence in the conversation for best is Kaleidoscope - which gives the equipped Servant 80% charge at the start of battle (100% if MLB) but at high-end content the damage is generally much more important. For a newer player Kscope is probably the better/more useful CE.
