@TofuuTofuu Rock% is already a category, tho with the only intent of getting a rock, not beating the game with it. Also, there is the caveman category which is pretty much that but without the "no upgrades" and "no damage" restrictions of the muck achievement. We find these two restrictions so hard that they're uncompetitive in a speedrun environment

Boat%
Reach the boat as fast as you can
Random seed only
Must show the menu in the video
Time starts at the first frame of fade-in and ends when the boat message is displayed in chat

Dinobam you can spawn on the boat which kind of breaks that category

I mean you could also spawn over a rock, but that category exists

powerup% get any powerup as fast as possible

guardian% - kill guardian

Rockless Catalouge - Get every item in the game except for "Rocks".

find ship% - just find the ship

OOooo i have a good one, FASTEST TO GET ALL THE PERKS!!!!! its actually a long game one and takes planning so should be fun

not sure if its been posted already but how about a speedrun for 1 gaurdian and also all of the gemstone gaurdians?

Gun percent its a plugin but id think it'd be fun

Full adamantite armor plus axe and pickaxe

Revive just revieve someone

complete achievement "Muck")
