I've seen people say that erlking was heavily nerfed or wasn't going all out in his fight at the end of canto 6.
but wasn't the whole point of him being an identity summoned through Cuck dough is that he's a summoned identity that's coming in full force? (unlike our IDs which are heavily nerfed compared to the real deal)
erlking is one of the few times where we beat an enemy at full force fair and square
