Almost A Hero Wiki

Trinket boxes can be purchased at the Shop or obtained as rewards in Adventure Mode, Gates of Gog and Season Challenge mode.

They are unlocked at stage 381 of Adventure Mode.

Each Trinket box costs 50 gems (can also be purchased with 300 aeon) and contains one single trinket with up to three bonuses.

After being opened, the trinket is immediately added to the collection. If there are no free trinket slots, the trinket box can't be opened.
