I prefer 25%, but whatever, 20 is fine, I think this is it, if I nerf him even more, he probably become too weak than the lore describe (the problem that many servants has.), as he has very low HP, even for Saber.

Maybe I would add some strengthen or interlude skills in the future, if you don't mind.
