Big Fish is an Event found exclusively in Act 1, The Exordium. The player must select one of three goodies dangling from the dungeon ceiling.
- Banana: Heal 1/3 of your max HP. If the player's HP is not divisible by 3, the HP gain is rounded down.
- Donut: Max HP +5. Like all HP gain, the extra hit points are healed when you get them.
- Box: Receive a Relic. Become Cursed (Regret). The Relic is a randomly-selected Common, Uncommon or Rare Relic.
The Donut is generally the best choice. The player probably doesn't need healing in Act 1, and Regret is a particularly nasty Curse.
If the path has more Merchants than usual, taking the Relic is safer - simply remove the Curse before facing the boss.
If you have Omamori with any charges left, it's a better choice to pick the Relic rather than the Donut.
