Builds For Henry

He kinda said no new weapon and no 5* exclusive skills and you say gronnowl and close counter ^^

He kills Reinhardt almost 100% of the time even with no extra "counter" skills.

Edit: btw you can even see on the calculator that he doesn't need the death blow that you gave him, because with it he overkills Reinhardt by more than 12dmg, so you don't even need it at all.

Uhm. What?
Unless Henry is -Def, he can be a pretty good counter for both Reinhardt and Brave Lyn, but not with this set. This set is... I don't know, I don't understand what you want to achieve with it. He doesn't need Deathblow to kill Reinhardt. Better A-slots are something offensive or something defensive, pick one. B-slot can either be Bowbreaker to counter Lyn as well, or Quick Reposte for more general use. The seal should be Distant Def 3, but maybe a deflect works, too, didn't test that yet. However, the only bane I would avoid is Atk, everything else still works marvelously on him.
I would really consider giving him a more offensive skill set with switching out his weapon, though. I did it with my own, and maaaaan, he just plain murders anyone in his path with his blade tome and up to 48 Spd. And he's only -Spd...
He also takes 0 damage from Rein WITHOUT the seal, so the seal is really just for Lyn.
