Gnoster is fun in musical and actual theme and feels distinct across the entire series. The actual fight is not exemplary, but it's still amusing for phase 2 to be literally just the Gurren Lagann "combination," with Moth just sitting on scorpion's head.

It's just a random chance on any gaol. If you're achevo hunting, just do single player runs and farm the gaols. There's guaranteed keys at every ruined church (treasure chest behind altar on fire assholes, ghosts, and golem, up in the rafters by jumping up behind the altar on bubble boys), so just charge through those then try the closest gaol.
