Cursed treasure bugged?

atleast from what i can tell it just lowers my time...
got 1 with 3 of them and got few token currencies from flesh merchant

9th temple going on but havent seen it give anything really?

any idea?

Cursed treasures aren't really treasure chests, but a loot buff that lasts for the remainder of the incursion.

For it to have effect, you need to kill mobs AFTER you get them and the loot will benefit from [increased quant/rarity?].

Don't open a chest before killing some mobs though, you'll timeout immediately.
