    Adds in mutations, things as small as slight changes to a player. Such as stick (longer reach) chicken (slower falling and immunity to fall dmg) to larger changes, such as squid or reconstruction. The power of said mutation increases with its rarity.

    There exist both runes and ruins. Ruins are much more common but have much worse chances of getting anything in the higher Rarities and cannot roll legendaries. Runes however are extremely rare but have significantly higher chances of getting better mutations.

    Deepslate. spawns everywhere in the overworld
    Desert. Spawns in the desert type biomes

    • Fixed a bug that caused ocean ruins to constantly give the same power/a very rare power
    • Reworked the assigning attribute system to make it work with other packs

    Amazing datapack! I've only seen human as the only common mutation and a couple of other mutations listed can't be seen in game, is this a bug?

    Thats not intended. I just checked and got Stick on my first try.

    Run this command and see you get something different.

    /function mutation:mutation_give/spinner/deepslate_ruin_effects

    I think what is likely happening is that you are just getting really unlucky and happenstance. Run that command 10 times and you should get something other than human. Please let me know how it goes!
