Big Fish

Big Fish is an Act 1 event where the player stands before a large fish that offers three choices: Eat (gain 12 HP and add a Parasite curse to your deck), Banana (gain 28 HP), or Drink (gain a random Rare relic but lose 5 max HP). The fish is a benign encounter with multiple positive options and no combat involved.

Big Fish offers three very different types of value. Banana (28 HP) is an exceptionally large heal that is almost always valuable in Act 1 when HP is precious. Drink provides a random Rare relic at the cost of 5 max HP — generally excellent value since Rare relics are very impactful. Eat provides a smaller heal but adds a Parasite curse (taking a random amount of damage when removing Parasite). Banana is typically the default best option unless your HP is already high and you need a relic more than healing.
