Hades II: (Workarounds)
Short answer
Suggested fix (unconfirmed): Equip the Lucky Tooth keepsake to rarify boons multiple times. Remember that keepsake effects only elevate rarity by one tier at a time.
The problem
aphrodite's mirror at max level does not rarify her boons to epic. only rare. same bugs on some of the other gods keepsakes. also the duo skill arterial spray doesn't change the color of Poseidon affects
What players suggest
That's not how it works, tho? Rarifying a boon goes up ONE level of rarity; you can rarify Rare boons to Epic, but not a Common boon to all the way to Epic.
Did this work for you?
