Listed here are the story-mode drops that grant this move as a completion reward. A character whose variant isn’t listed either starts with the move or unlocks it via Coach level / Free-starter (see the variants table above).

Brielle	Ignite Step	The Clash (Gold tier)

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	Slipstream Curve	4,310	37
Nina	Torque Line	4,310	37
Brielle	Ignite Step	4,310	37

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, Nina, and Brielle alike.

Star band	Level range	Coin per level: first → last	Band subtotal
Star 0 → 1	1–4	20 → 35	110
Star 1 → 2	5–12	45 → 80	500
Star 2 → 3	13–22	85 → 130	1,075
