Build Tools & Structures
Two datapacks that add builder's tools and things worth finding in the Overworld.
Two packs run alongside the server for features, both are the sort of thing you get used to fast and then can't imagine building without.
Jake's Build Tools
Various of craftable tools for builders, that take a lot of the hassle out of big projects. Tap any one below for its exact recipe!
Hold it, right-click a block, and it swaps in a random placeable block from your hotbar instead of whatever you were holding. Rotation looks the same as if you'd placed it by hand. Repairs in an anvil with the same material it's made of.
Copper IngotIf you want the deep-dive version (full item lists, version history, every mechanic we didn't cover), their official wiki is the source.
Dungeons and Taverns
Extra structures generate throughout the Overworld.
Firewatch towers, ruined towns, underground houses, badlands miner outposts, illager hideouts and camps, and wells scattered through most biomes.
The taverns are the ones worth going out of your way for. Each holds a villager you can level into a cartographer, and he sells maps and charts pointing at the rest of the pack's dungeons and ruins. One tavern is basically a quest board for everything else. Free treasure maps, as long as you're willing to make small talk with an NPC first.
