What is Useful Slime?
1 part
Useful Slime adds a retextured version of the slime sling and slime boots from Tinkers' Construct, plus a few other useful and fun slime items. Tinkers' Construct gets the credit for the original sling and boots.[1]
This pack ships Useful Slime 1.12.1, the NeoForge build.[2]
Where it sits in the quest book
The pack's quest book puts the mod in the Basic Armor chapter, in the quest "Slime Armor" quest. The quest asks you to obtain the Slime Helmet, Slime Chestplate, Slime Leggings and Slime Boots.[3]
The quest text calls it a fun armor for bouncing and climbing everywhere all the time.[3]
How do you get started with Useful Slime?
4 parts
Useful Slime adds slime armor and a few other slime items with handy abilities. Every item below has a real in-pack recipe, so I'll point you to the recipe blocks and walk through a sensible order to build things in.[1][4]
Start with the Slime Boots
Make Slime Boots first. The pack's quest book describes the slime armor as a fun set for bouncing and climbing everywhere, and the boots are the bouncing part.[3][4]

Recipe id: usefulslime:slime_boots
The mod has a boot surfing option: when it is enabled, holding the jump key lets you keep your momentum and keep bouncing endlessly below 1.5 blocks of fall distance. There is also a setting for whether bouncing damages the boots.[5]
Finish the armor set
Next, complete the set. The quest "Slime Armor" quest in the Basic Armor chapter asks for the helmet, chestplate, leggings and boots, so it works as a handy checklist.[3]
- Slime Helmet: the mod has a setting for whether the helmet takes damage when you climb on the ceiling.[5]
- Slime Chestplate and Slime Leggings: the mod has a setting for whether these take damage from wall climbing, not counting blocks that are already climbable.[5]

Add the Slime Sling
The Slime Sling is a retextured version of the slime sling from Tinkers' Construct, and it is a good next item once your armor is done.[1][4]

How does Useful Slime work?
3 parts
Useful Slime is a simple mod. The sources describe it as slime armor and items with special abilities, and nothing in them mentions machines, multiblocks, power, fluids or automation. So the mechanics below are mostly about how the armor and blocks behave, and which options can change that.[1][5]
Slime armor abilities
The Slime Boots and Slime Sling are retextured versions of the slime boots and slime sling from Tinkers' Construct. The mod also adds the Slime Helmet, Slime Chestplate and Slime Leggings.[1][4]
- Slime Boots let you bounce, and an option can make that bouncing damage the boots.[5]
- Boot surfing is another option. When it is on, holding the jump key lets you keep your momentum and bounce endlessly, as long as your fall distance is below 1.5 blocks.[5]
- The Slime Helmet lets you climb on the ceiling, and an option can make that damage the helmet.[5]
- The Slime Chestplate and Slime Leggings allow wall climbing, and an option can make that damage them. Blocks that are already climbable don't count.[5]
I can't show you the pack's values for these options. The sources only give the option descriptions, and no config files for this mod were available. Check the in-game config screen to see whether each damage option is on in your world.[5]
Slippery Slime Block
The Slippery Slime Block has a configurable maximum speed for any entity standing on it. The option's own description warns that a high value can cause lag, because entities can be sent hundreds or thousands of blocks away.[5]
Crafting the key items
All of the mod's items are crafted in the pack with ordinary crafting recipes, and none of them need a machine. These are the recipes for the items covered above.[4]

Unverified The sources don't explain how the Bouncy Slime Block or Jello behave in play, how the Slime Sling is used, or what the pack's actual config values are. Test them in a creative world before you build around them.
How do you progress through Useful Slime?
2 parts
Useful Slime has no tier ladder in the sources for this pack. Every item it adds is made in a crafting grid, and the quest book gives the mod one quest: "Slime Armor" quest in the Basic Armor chapter. That quest is where your progression with the mod starts.[3][4]
The quest: Slime Armor
The Slime Armor quest asks you to hand in the full set: Slime Helmet, Slime Chestplate, Slime Leggings and Slime Boots. The quest text calls it a fun armor for bouncing and climbing everywhere all the time.[3]
Here are the in-pack recipes for each piece. The recipe dump lists all of them as mod recipes.[4]

Other things to craft
The quest doesn't cover the rest of the mod, but these items all have crafting recipes in the pack. First up is the Slime Sling.[3][4]

Which All the Mods 10: To the Sky quests use Useful Slime?
This mod shows up in one quest in the pack: "Slime Armor" quest, which sits in the Basic Armor chapter.[3]
The quest is a checklist with one task per piece of the full set, so you need all of these items:[3]
The quest text describes it as a fun armor for bouncing and climbing everywhere all the time.[3]
