What is Useful Slime?
2 parts
Useful Slime is a small mod that adds slime armor and items with handy abilities. Its core is a retextured version of the slime sling and slime boots from Tinkers' Construct, plus a few other useful and fun slime items.[1]
It's a good fit if you like the Tinkers' Construct slime gear for getting around but want it as standalone items, or if you just like playful movement gadgets in your base and exploration kit.[1]
Version in the pack
The pack ships Useful Slime 1.12.1, the NeoForge build for Minecraft 1.21. It has been part of the pack since version 1.0 or earlier.[2]
Good to know
Unverified The sources don't show where Useful Slime fits in the pack's progression. No quests, ATM Star path steps or in-jar guidebook were found for it, so treat it as an optional extra rather than a required step.
How do you get started with Useful Slime?
4 parts
Same as in the All the Mods 10: To the Sky 2.0.4 guide
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][3]
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]

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 a quest in "?" in the Basic Armor chapter asks for the helmet, chestplate, leggings and boots, so it works as a handy checklist.[4]
- 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][3]

How does Useful Slime work?
3 parts
Same as in the All the Mods 10: To the Sky 2.0.4 guide
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][3]
- 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.[3]

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?
3 parts
Useful Slime is a small mod, and in this pack every item it adds comes from an ordinary crafting recipe. The sources here show no tier structure for it, so the groups below are just a handy way to browse what you can make. Each recipe block shows the exact in-pack recipe.[6]
Unverified The sources here show no quests involving this mod, so a quest-driven progression path for it is not confirmed.
Slime blocks
The mod adds the Bouncy Slime Block and the Slippery Slime Block. Both are shaped crafting recipes that start from a regular slime block.[6]

Recipe id: usefulslime:slippery_slime_block
Slime armor and the sling
The armor set is the Slime Helmet, Slime Chestplate, Slime Leggings and Slime Boots. Each piece is a shaped crafting recipe made from slime balls and slime blocks.[6]

The Slime Sling is also a shaped crafting recipe. On top of the slime ball and slime block it needs string, so grab some before you craft it.[6]

Jello
Jello is a shapeless recipe made from a slime ball and sugar, so you don't need to worry about the layout in the crafting grid.[6]
What changed in Useful Slime between versions?
1 part
All the Mods 10: To the Sky 1.0.2 ships with Useful Slime 1.12.1. The mod has been in the pack since 1.0 or earlier, so you won't find an older or newer version of it in this release.[2]
Useful Slime 1.12.1
- Slippery slime blocks now stack to 16.[7]
- The slippery slime block recipe was improved. The changelog doesn't say what exactly changed, so check the in-game recipe viewer for the current version.[7]
- The Russian translation was updated.[7]
Unverified The pack's own changelogs have no entries for this mod, so there is no record here of what changed for Useful Slime between pack releases.
