Finn
Finn hands out quests, and quests are one of the two confirmed XP sources alongside catching fish.
What quests look like
Quests are random and general, such as:
- Catch ___ fish
- Catch a 300+ kg fish
That second kind is why the Strength stat on your rod matters: see Fish weight.
Rewards
Likely coins, XP, clams or items depending on the quest. Harder quests are one of the ways clams are earned.
Location
Probably not on Coconut Cove. Which island he lives on is undecided, once it is settled, having that island unlocked is all you need to use him.
Awaiting data
The quest pool, rewards, refresh rate, and whether there is a limit on active quests.
