Excavar

Holding the mod's key while mining makes the tool break a group of blocks in a single action, with a default limit of 16 blocks per break. Excavar works only on blocks the tool can correctly harvest, so a pickaxe clears connected stone while blocks that need another tool are left alone. The config is simple, and the block limit and related settings can be adjusted to suit a world or server.

Excavar is a lightweight alternative to FTB Ultimine for players who want a smaller mod with fewer options. It does not go as far as Ultimine's shapes and extra stuff, and it is not meant to replace it. Blocks that break in an excavation drop their items as usual, and those drops are sent into the player's inventory, while the mod does not make blocks like cobblestone or netherrack dig faster than they would with the right tool.

The mod runs on Forge and NeoForge across 25 release versions, 1.16.5 – 26.3, and it is open source under the Apache License 2.0. Client and server must both run it, and the 26.1 update is documented in the author's porting notes. Source code, an issue tracker and a wiki are linked from the project.
