Rewards from challenge event. Legendary- Stage 7
You got 2 chests. That is pretty rare. The players trying to get those top scores search for those.
I had like 6 chests in total from this event idk if they increased the % of loot or I’m just lucky.
Someone told me they thought they lowered the chest occurrences lol. You must be getting theirs ;). It is random like summons. Sometimes you’re lucky and others you’re not. Congrats!
