Enchantments are a brand new type of modifier that will apply directly to your cards. Similar to upgrades, these improve a card's performance, and may unlock some exciting combo potential.
Unlike their evil counterpart Afflictions, Enchantments you apply will remain until the end of the run. However, like almost everything in the Spire, a positive gain often comes with negative repercussions.
We don't know much yet, but check back soon after release for more updates.
