Ok sorry for the corny title but I was just testing out the Gladiator buff and how his gimmick was now that his charges don't fall off. He is..something now.
If you have a 7 star gladiator, select armor as attack bonus and rush into specials while unstoppable. Just make sure those specials don't apply bleed or some other debuff (e.g. Dani's last hit applies neuroshock so you gotta dodge that)

For clarification, yes I took all the sp2s to the face. You don't need to look for complex openings where you do two hits and back out and stuff.
No the damage is not just from sp2s, I messed up here and there.
