I killed Groal the Gay with poisoned cogflies and the cheese-strat.
And I am not sorry.
You have the worst runback in the game, even including the hidden bench.
You have the mandatory arena fight just before him.
And you have the potential to be blocked from healing at any point.
This is not a boss that deserves the effort of beating it fairly. This is a boss that in all honesty deserved me simply downloading an invincibility mod and killing it at entirely at my own pace, and not doing that was more respect than it deserved.
What an absolute pile of shit of a boss, in every way.
