He looks very, very strong. The broken kind of strong. Not only does Becket is a Ruler, he is also able to achieve a 50% defense up for 3 turns using his 1st and 3rd skill. This means he's going to end up taking 25% damage from most classes at almost any time. Topped with a 3 times debuff immunity means there's no way you can reduce his defense--as if the 25% magic resistance isn't enough. To put the icing on the cake, his HP is also on the higher end of SSRs, ensuring that this person right here is unkillable. And he doesn't even need 3 hit invincibility to prove that.

His passives stack together. NP gain buffs stack with Arts buffs, giving his AQA a total of 40% NP gain. The NP alone gives him 21% NP on refund... and an NPAA chain gives him 71% NP. His base NP gain is indeed lower than normal, but his passives and battery makes it up for it, so you have something like what Hokusai has. (And even with Hokusai's NP effect too). With that 150% extra damage, he won't have problems dealing some damage to 1/3 of all Servants in the game.

I think you've given Becket way too much defensive power. I also noticed you've upped the defense to 3 turns when Protection of the Faith is supposed to only have 1 turn defense up.
