With Sand Bounties, whenever a player defeats a Husk, there is a 50 % chance for it to drop additional items. These additional drops are based on what biome the Husk dies in.
Valid biomes for additional drops are:
- Desert -> Sand
- Badlands, Eroded Badlands and Wooded Badlands -> Red Sand
If the Husk is on fire it will drop Glass blocks instead of Sand / Red Sand.
