Discovery is a colorless Uncommon Skill that that presents you with 3 random cards from the card pool of the character you are playing, from which you may choose one to add to your hand. The card added to your hand has its cost reduced to 0 for the turn. Discovery then Exhausts.
Prismatic Shard does not affect the variety of colors of the card it generated. It however is affected by Run Modifiers, which could potentially allow it to present you with more than one color of cards.
Upgrading Discovery causes it to no longer Exhaust.
It can only generate a card that are available through shop and rewards. It cannot generate a healing card.
