Mobius

Mobs are divided into six difficulty tiers, and the tier is shown as a number of symbols above each mob's head. A higher tier lowers the chance of spawning, and the enhancement raises only the mob's health and damage. Tier 6 mobs carry a 40% chance of dropping a special item, and mobs that have been enhanced also drop additional loot, with quality set by their tier. The M key opens a settings menu where HP, damage and spawn chance can be adjusted, and the mob enhancement can be disabled there.

New materials sit between the vanilla tiers. Steel Ingot falls between iron and diamond and is smelted in a Blast Furnace from iron ingots over a long process. Gilded Copper Ingot is crafted from large amounts of copper and gold and gives better diamond tools. Jade Ingot is the top-tier material, with a long crafting chain that makes it rare. Tea is brewed in a Brewing Stand from Water Bottles and tea leaves, which come from tea bushes in jungles and are gathered with modded Tea Tongs. The leaves must then be dried into tea shreds before brewing. Trash Chest holds 22 slots that empty with a button, and Steel Chest holds 71 slots.
