Fortress Def/Res or Brazen Def/Res?

just dumpster the attack and get the Fortress def res

Fortress because no condition and you don’t use his attack. But just remember that Kliff is one of the best bois in this game before you fodder him. He needs love

Fortress is safer because it's ready from the start of the battle and you won't ever heal yourself out of it. (Granted, if you actually heal yourself out, you probably have the HP to take the extra hits)
