Tip in case you didn't know; throwing a jellyfish at a creature stuns it, which often leaves great opportunity to kill it. That should be used for during Hunter's run because it's really hard

ngl I bought it after beating survivor, I haven’t beaten hunter yet even though I’ve beaten saint at this point, also I think that monk’s campaign is just survivor’s but easier (less food required and less aggressive creatures)

also getting all of the arena content would be quite a grind, plus downpour adds more that you’d have to find anyways.

Although if you do want to stick to just vanilla I’m pretty sure the discord server has a bunch of difficult challenges you can try.
