How to Get the Boss Sprite in Fortnite

The Boss Sprite is the best survival Sprite — a flat +25 max HP and Shield at Level 5. It drops at 4.45% per chest. Once you've collected it once, you can summon the Boss Sprite again for 4,500 Sprite Dust — usually faster than fishing for it in chests.
Where to find the Boss Sprite
The Boss Sprite drops from Sprite Chests at roughly 4.45%. Sprite Chests are the guaranteed-Sprite source, so open every one you find; it's often claimed from defeating a powerful adversary.
Ability — and is it worth chasing?
Ability: Grants an increase to your max HP and Shield. (5 → 10 → 15 → 20 → 25 HP/Shield across Levels 1–5.)
Verdict: S-tier for late game. If you want to win rather than frag, prioritise this.
Fastest way to get it
Open Sprite Chests during any Rate Up for the best odds, and summon it for 4,500 Dust if RNG isn't kind. Farm Sprite Dust by extracting duplicates (a Gummy variant adds +10% Dust per extraction).
