Plague of the Red Death.

[Lilly112]

Now this item set is possibly 'the' most OP set in the game. However it took me nearly three months of straight up grave-robbing to get it, so I have a suggestion.

Make it easier to get, the chance of finding it a lot higher, but make the getting the actual items harder, like you have to fight the Red Death to get it.

I think the point is that the Red Death is supposed to take a long time to acquire. Also finding it is not random.
