Hero Progression Costs — Full Tables

Universal costs that apply to every hero: XP per level, star fragments, skill books, exclusive equipment, and the per-fifth star stat bonuses.

Star & Exclusive Equipment fragment costs

Each star level is bought in 5 steps. Cost is identical for every hero regardless of tier — which is exactly why S heroes are the efficient target.

Level	Star fragments/step	Star total/level	Star cumulative	EE fragments/step	EE total/level	EE cumulative
1	5	25	25	5	25	25
2	10	50	75	10	50	75
3	20	100	175	20	100	175
4	60	300	475	30	150	325
5	100	500	975	50	250	575

Stat bonus per star step (universal-chart values)

The troop-size column is universal — verified against Scarlett. The ATK/DEF columns scale per-hero (Scarlett’s steps showed +338/+336 where this chart says +487/+487); treat them as the shape, not the exact number.
