Since I've been unlucky enough to not be able to finish Shiki's event, I only have grailed Kojiro (75-80) and..... Stheno (50, not gonna ascend her >.<) as assassin. I managed to NP2 him for no reason..
Is it worth it-
This servent is good to punish the other servents you don't alike much example like Merlin and Queen Medb.
His NP is art type but it does not recover the NP too much (maybe about 10%) but he has the effect to reduce enemy's charge so yeah it is worth to use him~
If you don't have Shiki and/or Jack, he is worth it. He is good star generator and can fit in Critical Arts Team.
