Certificates and Mine-Go Juice¶
There are three ways to Ultimine. They stack: whatever you have unlocked for the tool in your hand is what you can use.
| Unlocks | For | Lasts | |
|---|---|---|---|
| Shape Certificate | One shape | One tool | For good |
| Mine-Go Juice | Every shape | One tool | While the effect lasts |
| Miner Certificate | Every shape | Any item | For good |
Shape Certificates¶
Each time a Mining Skill Card reaches a new tier, it lets you claim one Shape Certificate for that card's tool.
- Open the card in the Skills Record and claim the tier's reward.
- Pick a shape. The choice is that tier's list, plus any shape from an earlier tier you passed over.
- Use the certificate you receive. The shape is learned for that tool permanently.

The default lists:
| Tier | Shapes offered |
|---|---|
| Novice | Small Square |
| Apprentice | Escape Tunnel, Mining Tunnel |
| Adept | Small Tunnel, Large Tunnel |
Servers can change the lists, and decide which certificate picks up shapes that no list names (such as ones other mods add). A higher certificate tier also raises how many blocks one Ultimine can break with that tool.
Holding a tool with no shape learned shows "No Shape Learned" in FTB Ultimine's shape display.

Shape Selector¶
The Shape Selector is a craftable item that lists the shapes and lets you assign the one you want to the tool you're using, instead of cycling through them.
Mine-Go Juice¶
Mine-Go Juice is a potion with one variant per tool. While its effect lasts, you can Ultimine with every shape using that tool.
- It is brewed in a brewing stand from a Novice, Apprentice or Adept Mining Skill Card that has potion points left (the pips along the bottom of the card). Brewing spends them, and the card gets a full set again when it tiers up.
- The higher the card's tier, the longer the juice lasts.
- Splash and lingering versions and tipped arrows exist too.
- With the
tier_up_tasteserver setting on, a card that tiers up gives you a short free taste of its juice.
Miner Certificate¶
The Miner Certificate is the end of the road: Ultimine with every shape, with any item, for good.
Craft it from a paper and all four Mastered cards (pickaxe, axe, shovel and hoe), then use it.
Completion Envelope (Legacy mode)¶
In Legacy mode the certificate starts as a sealed Completion Envelope, crafted from paper and four tools. It asks you to mine a number of ores; once you have, it opens into the Miner Certificate.
