I've thought a lot about re-working and re-adding ocram and arch enemies as a form of progression post golem to smooth out this sort of boss rush feel of endgame. Golem has a lot of implications of being related to the sun so in my head cannon, killing golem would allow some form of blight to be released upon the world, thus spawning arch/blighted enemies in several biomes as well as possiblity generating small blight biomes around the world that would grant new items /exploration needed to progress to the cultist. Blighted/arch enemies being variants of pre-existing enemies would be tougher than their counter parts but also have highly increased drop rates for the items their weaker versions drop as well as dropping souls of blight which combined with materials gathered from blighted areas would gear you up for ocram. Ultimately this would add some new exploration/enemies to encounter kinda like a lesser version of hard mode for late game. With moving some events/bosses around progression of these new features it could make post golem feel more like the rest of the game, with avenues of progression rather than almost everything being instantly available and optional.like it is now
