Tumbleweed
What Tumbleweeds Do
Tumbleweeds are rolling plants that spawn in dry, open terrain and drift with the wind. When one passes near you, it can be broken for loot, and the drop is random rather than fixed — so the same tumbleweed may yield something trivial or something worth chasing.
Loot Tiers
Which items a tumbleweed can drop is controlled by loot-tier data packs. A data pack defines the possible drops for each tier, letting pack authors expand or restrict the loot pool without changing the mod itself. If you want different rewards, that is the place to look.
Configuration
Every config option is exposed for tuning: spawn behaviour, how tumbleweeds move, and what they drop. Adjust these to make tumbleweeds rarer, more common, or harmless scenery. Because the mod is small, the config is the main way to shape how it feels in your world.
