⚠️ DO NOT USE ON PRE-EXISTING WORLD THAT YOU CARE ABOUT ⚠️
Makes every block you break spawn a Silverfish, just like a Vanilla infested block would, however in this case, the block will still drop.
Hitting a Silverfish will make 1-3 more Silverfish emerge from blocks, slowly destroying the world the more you try and fight them.
