How will the corruption content work, will we have to choose one corruption path or can we do all of them at once? You know become a monstrosity beyond comprehesion, a being that shouldn't exist.
It will be possible to mix some corruptions (aether/nether) for a unique result, and you can have multiple 20%+, but for the most part going past 50% in one will lock you out of 50%+ of others. Most do not play nice together and fundamentally cannot.
