AwakenedSilverfish

Silverfish keep their familiar behavior, but a bark beetle that generates in stone or in eroded insect blocks is twice as sturdy, with 16 maximum health and 2 attack damage. Generation is rarer than in the original, since a bark beetle spawns with only a 10% chance when a stone block is destroyed, and then 1 to 5 beetles appear.

Each beetle rolls a rarity: normal, magic, rare or legendary, weighted 40%, 30%, 20% and 10%. Higher rarity adds affixes and raises the number of items dropped on death, up to 4 random minerals and 12 dropped items for a legendary beetle. Its attacks also carry a 10% base critical strike chance and 150% critical damage, and the mod adds attribute effects shown as potion icons. The mod runs on client and server, so both the server and every player need it, and it is released under the MIT License as open source for NeoForge 1.21 with Cimdy as the author.
