Bugs Notice
This mod currently has some bugs (with sandworms not despawning), since it was mainly made for a Youtube video.
Please don't use the mod for a world that doesn't have commands enabled, since you may need to use the following commands to clean up an old sandworm entity if it didn't despawn properly:
- /kill @e[type=entersandworm:soulsandworm]
- /kill @e[type=entersandworm:soulsandwormbody]
- /kill @e[type=entersandworm:soulsandwormhead]
Information
this is a fabric mod for 1.21/1.21.1 that adds sandworms to Minecraft, inspired by Dune. they can be enabled for soul sand valleys in the nether and/or deserts in the overworld through the config. soul sandworms are spawned in when a player breaks a soul sand block (in a soul sand valley) or sand block (in a desert) twice in under 90 seconds.
the mod can be used on neoforge or forge using sinytra connector.
Gameplay Details
a sandworm is extremely powerful and able to "eat" and kill you instantly if you collide with its head.the best method to kill them is to use explosives to blow up their head. upon death, they will drop a tooth item which can be used alongside a netherite ingot and a stick to craft a Crysknife: a sword more powerful than a netherite sword.
