XP Trap

I don't know how to make them, so I'd recommend looking them up on YouTube yourself, but here are some I know of: Overworld: Golem Trap, Trap Towers (Mixed, Creeper-only, Spider-only are common; sorting all mobs is also possible), Slime Trap Nether: Piglin Trap End: Enderman Trap (Best for XP outside of potion-related farms), Shulker Trap Other (Biome-specific or item-based): Drowned Trap, Fish Farm (Different from an automatic fishing machine; for bone meal), Guardian Trap, Magma Cube Trap, Wither Skeleton Trap, Potion Farms (e.g., for lingering or splash potions; the host mob can vary, but I think an Allay + Campfire works well), Raid Farm, Boss Farms (Instant kill devices using arrows and wind charge are also possible) Bonus (Speculation): It seems like an Enderman trap could be made in the Warped Forest in the Nether, and a Skeleton trap in the Soul Sand Valley. However, it's definitely not worth the effort. It's more reliable to make an Enderman trap in the End, and bone meal can be increased with a bone meal machine using shulkers. Arrows and such probably won't be an issue either.

Good luck with trap making! If you're aiming for EXP, I really think Daman is the only choice. It's a classic for Minecraft players, passed down since ancient times, alongside TT.
