Dream Catcher
Dream Catcher is a common relic that adds a bonus option whenever you rest at a campfire: instead of healing or upgrading, you may obtain a card from a reward pool. This gives you a third choice at every Rest Site, effectively making campfires more flexible and potentially more valuable if the offered card is something your deck needs.
The relic's value depends on whether you find yourself wanting cards at rest sites. In runs where healing and upgrading feel mandatory, the dream-catching option may rarely see use. But in runs where your HP is healthy and your deck is well-upgraded, having the option to snag an extra useful card is significant free value. Dream Catcher is particularly attractive early in a run when your deck is still taking shape, and it synergizes with Singing Bowl if you prefer taking Max HP over cards — the relic gives you a third option alongside upgrading to occasionally shop for the right card.
