Location:
Mines, Floors 40-79.
Strategy:
Dust Sprites are small, fast enemies that explode upon death, dealing damage if you're too close. They are not a traditional 'boss' but are important for a monster eradication goal. Use a fast weapon like a Dagger or a quick sword. Try to hit them from a distance or move away quickly after a kill to avoid explosion damage. They are weak to no specific element. Focus on clearing them efficiently.
Rewards:
Coal (high drop rate), occasional rings. Defeating 500 Dust Sprites completes a Monster Eradication Goal, rewarding the Burglar's Ring (doubles monster loot drops).
