Overflowing Cup is a Keepsake obtained by giving the god Dionysus a gift of Nectar before accepting one of his messages. Its effects can be enhanced by clearing enough encounters with the keepsake equipped.
The next Boon you find will be from Dionysus. His blessings have +10/15/20% chance to be Rare or better.
From Dionysus; you share a Jubilant Bond
Two free spirits, though far apart, still can brighten each other's days.
- While the guaranteed Boon only works once per run and not per biome, the rarity bonus remains for the entire duration of carrying the keepsake.
