Ingame Book

An ingame guide to the content of the mod, it covers everything you need to play the mod. Shapeless recipe:

Book Recipe


Empty Slime Capsule

One of the most basic items in the mod. Serves as 'ammo' for the Slimalyser (see below) as well as key components in the crafting recipes in this mod.


 Breeding Catalyst

Right click a coloured slime with this to activate its latent breeding capabilities. Once two 'activated' slimes breed, their offspring will automatically be able to breed.

Breeding Catalyst

 The Slimalyser

The Slimalyser is your main tool for engineering the colour of your slimes, use it (right-click) on a coloured slime with 'Empty Slime Capsules' in your inventory to take a sample. Once you have collected your sample sneak-use the Slimalyser to open it's gui.

The Slimalyser



The Slimalyser Gui

Place in either of the top slots (left or right) an item or 'Filled Slime Capsule' and the gui will change accordingly to tell you how similar the two items are in colour. Similarities of greater that 90% suggests the slime is capable of dropping that item! If an Item is unable to be added to one of the slots that means its currently unable to be dropped by slimes.
