SXD's Random Blocks

Each block in the set belongs to one of five tiers, from Low Random Block up to the top tier. A Low block drops a single random item when broken, a Medium block drops up to 10 items from 1 to 10 types, a High block up to 30 items from 1 to 30 types, a Top block up to 64 items from 1 to 64 types, and the highest tier up to 128 items from 1 to 128 types. The blocks are blast-proof, can be broken without much effort, and are collected in a dedicated creative tab.

The drop pool covers a large number of vanilla and modded items, and an intelligent filter keeps out items such as command blocks and barriers. Drop logic is optimized to reduce game lag. The mod is released under the MIT License and is open source, with its source code and issue tracker public. It is published for Forge only, for 1.20.1, and runs on client and server, so the server and every player need it.
