Frostusk
Frostusk — epic fossil pet. A mammoth thawed out to work the Ball Factory - tireless, and strong enough to carry the hopper.
Overview
Frostusk is an epic regular pet: A mammoth thawed out to work the Ball Factory - tireless, and strong enough to carry the hopper.
It is a regular pet that never appears in a pet crate. It is revived from a fossil in the Boneyard and carries 3 abilities unlocked one per star — see How to get.
Every regular and limited pet carries a nature — one of 13, rolled per copy — that raises one job by 15% and lowers another by 10% — the jobs are MINING (dig power on expeditions), FORGE (work speed at a Ball Factory machine), CHESTS (its own share of hoard chest speed), GATES (damage to the hoard gate); a few natures are neutral. Elusive pets have none, and the board never reads natures.
One pet, one job. A single copy can only be in one place at a time on the board's side: on the board, on an expedition or working a Ball Factory machine. A pet that is working somewhere else is drawn greyed out in the Pets inventory with a gold banner naming the place (EXPEDITION, FACTORY…), and tapping it to equip only tells you where it is busy — take it off that job first. The Hoard is its own screen and can use any pet you own, even one on the board. A pet cannot be traded while it is working or in the Hoard, and a pet in a pending trade can't be equipped or put to work until the trade ends.
Abilities
This pet has 3 abilities and unlocks them one per star: the first is live from the day you get it, the second needs 2★, the third 3★ (see fusion below).
| ★ | Ability | Lv 1 | Lv 25 | Lv 50 | Lv 75 | Lv 100 | Charm |
|---|---|---|---|---|---|---|---|
| 1★ | Cold Forge | +0.00% | +21% | +42% | +64% | +85% | — |
| 2★ | Tusk Rack | +0.00% | +7.3% | +15% | +22% | +30% | — |
| 3★ | Frost Sift | +0.00% | +4.8% | +9.9% | +15% | +20% | — |
- Cold Forge — Working a Ball Factory machine, it forges this much faster.
- Tusk Rack — The machine it works holds this many more balls and bars.
- Frost Sift — Its machine drops fuel and machine upgrades this much more often.
Stars and fusion
Fuse 3 copies at the same star into one at the next — guaranteed, at the Fusion forge. The XP invested in all three copies is pooled into the result.
| Fuse | Needs | Essence |
|---|---|---|
| 1★ → 2★ | 3 × 1★ Frostusk |  2,000 |
| 2★ → 3★ | 3 × 2★ Frostusk | 6,000 |
Each star switches on the next ability in the table above.
A 3★ copy can become shiny by fusing an owned shiny Frostusk into it for 10,000 — see Shiny pets.
Levelling

Salvage
Salvaging a copy yields 800, plus a 20% chance of 
80 on top. See Pet Salvage.
How to get
- Revived in the Boneyard from the FROZEN TUSK (a World 2 fossil, 96 hours in the revival chamber, paid in that world's bars). Never in the pet crates — see Fossils and fossil pets
- The fossil itself is a rare expedition find (0.6% per hour of a completed trip in a World 2 mine) and its forge recipe is learned by uncovering the whole fossil in a Boneyard dig.
- Revive it again for more copies — three fuse into the next star, and each star switches on the next ability.
