Rat Upgrades Guide: From Basic to Advanced
Overview
This guide covers all rat upgrades, from basic to advanced, with crafting recipes and uses.
Rat Upgrade: Basic
The 
Rat Upgrade: Basic is the foundation for every other upgrade. It can be crafted in two ways: a shaped recipe using eight 
Cheese arranged around the crafting grid, or a shapeless recipe combining a 
Rat Upgrade Block with nothing else.
Health Upgrade
The 
Rat Upgrade: Health increases a rat's maximum health. Craft it with four 
Bread, four 
Glistering Melon Slice, and one Rat Upgrade: Basic in a shaped pattern.
Strength Upgrade
The 
Rat Upgrade: Strength boosts a rat's attack power. The shaped recipe requires four bones (any type from the forge bone tag), two 
Iron Sword, two 
Iron Ingot, and one Rat Upgrade: Basic.
Speed Upgrade
The 
Rat Upgrade: Speed makes a rat move faster. To craft it, combine four 
Redstone Dust, four blocks of redstone (any forge storage block tag for redstone), and one Rat Upgrade: Basic in a shaped arrangement.
Armor Upgrade
The 
Rat Upgrade: Armor gives a rat protective plating. The shaped recipe uses six Iron Ingot, one Shield, one Rat Upgrade: Basic, and one block of iron (any forge storage block tag for iron).
Warrior Upgrade
The 
Rat Upgrade: Warrior is the most advanced upgrade, combining the effects of health, strength, and armor into a single powerful enhancement. Its shaped recipe requires four diamonds (any forge gem tag for diamond), one 
Diamond Sword, one Rat Upgrade: Health, one Rat Upgrade: Strength, one Rat Upgrade: Armor, and one block of diamond (any forge storage block tag for diamond).
How Upgrades Are Used
All upgrades are applied directly to a rat. Each upgrade occupies a slot on the rat's upgrade interface, and a rat can hold multiple upgrades simultaneously. The Rat Upgrade: Basic is only useful as a crafting component—it provides no benefit on its own. The health, strength, speed, and armor upgrades each modify one specific stat. The Warrior upgrade is a composite that grants the combined benefits of the health, strength, and armor upgrades in a single slot, which is useful when you want to save upgrade slots for other purposes.
Crafting Order
Start by making a Rat Upgrade: Basic, then use it to craft the health, strength, speed, or armor upgrades. To make a Warrior upgrade, you must first have the health, strength, and armor upgrades ready, since they are all required ingredients. Note that the Warrior upgrade does not require a Rat Upgrade: Basic directly, but it does require the three stat upgrades that each needed one.
