How merging and level 4 work
Patch 1.2.0 / Balance 24. Facts below are tied to a source checked on 2026-10-01. Anything still open is marked unconfirmed.
The copy rule
From the community mechanics page that quotes the shop rules: three level 1 copies make a level 2, then two level 2 copies make a level 3. Standard merging stops at level 3. Special level-up effects can reach level 4.
Special upgrades to level 4
Ultra Candy is listed at an in-game price of $60. The Professor encounter can also grant the special level-up. The community trinket card for Mega Upgrade Disc says the next monster merged to level 3 becomes level 4 instead. These are sourced examples, not an exhaustive event list or a guaranteed shop offer.
| Item | In-game price in the notes |
|---|---|
| Basic Candy | $30 |
| Rare Candy | $40 |
| Ultra Candy | $60 |
| Crimson Ticket | $30 after 1.2.0 (was $50) |
| Green Stone, Blue Ticket, Lucky Coin | $0 in the item table |
Sell value
Community documentation calculates resale from base cost times the level multiplier, adds stored purchase discounts, divides by two and rounds up, then adds bonus sell value. Its level-1 to level-3 multipliers are 1, 3 and 6. The official 1.0.0 patch says level 4 now resells at the level-3 price; the community page's older multiplier of 12 for level 4 is not a current rule. Use the client tooltip for a modified unit's final price.
