Wheel of Change
Wheel of Change is a shared event (appearing in Acts 1-3) where the player spins a large wheel that lands on a random outcome. Possible results include gaining gold, gaining a card, gaining a relic, gaining max HP, losing gold, losing HP, receiving a Curse card, or having a card transformed. The wheel spins once and the result is final.
Wheel of Change is pure luck with no meaningful player agency. Its average expected value is slightly positive overall, but individual results can range from excellent (gaining a relic or max HP) to negative (losing gold or receiving a Curse). There is no optimal strategy beyond simply accepting the spin. Players who encounter this event must simply adapt to whatever outcome occurs. The unpredictability makes it one of the game's more polarizing events.
