What happens if I give kassy the ring of fate and what happens if I don't? I've got 2 saves one with full purity and one with full corruption. Im just curious.
Some spoilers here. Pure PC and romancing Kass route.
Calise is Kass. If you romance Kass as pure -> it seems (to me) her goal is to protect PC from corruption - so she doesn't even take the ring from you. Here is full description of Usage.
If i remember correctly Kass threats the ring somewhat like engagement ring.
