How are sea creature chances calculated?
Each creature has a weight, and your chance to catch it is that weight divided by the total weight of every creature you can catch in your current spot. Heavier creatures appear more often than lighter ones.
How do bait, hooks and pets change my odds?
Your bait, hooks and pets shift those weights, nudging the pool toward the creatures you want. Because the odds are relative, boosting one creature's weight lowers the share held by the rest.
- Pick Water or Lava and your location, since the pool differs by spot
- Set bait, hooks and pets to reshape the weights
- Each chance is one creature's weight over the total
