Upgrade cost
Coin cost to level the move from fresh to the rarity’s max level. Coin tables are character-keyed, so per-character values above are what the player pays.
| Character | Variant | Total coin | Max level |
|---|---|---|---|
| Lilly | Obsidian Spine | 38,810 | 60 |
| Jasmine | Prism Balance | 38,810 | 60 |
| Nina | Vector Cross | 38,810 | 60 |
Per-level cost ladder
Each star band spans a run of consecutive levels. Coin cost climbs linearly within a band and jumps at band boundaries. The ladder is identical for all three variants (it’s character + rarity keyed, not per-move), so one table covers Lilly, Jasmine, and Nina alike.
| Star band | Level range | Coin per level: first → last | Band subtotal |
|---|---|---|---|
| Star 0 → 1 | 1–5 | 40 → 120 | 400 |
| Star 1 → 2 | 6–13 | 140 → 280 | 1,680 |
| Star 2 → 3 | 14–25 | 310 → 530 | 5,040 |
| Star 3 → 4 | 26–40 | 560 → 840 | 10,500 |
Star-up element recipes
