Gathering Isles
Floating islets reached from Sunshire's Sky Dock. Their wild Mogas always match your strongest Moga's level, and every win gathers resources: each location has its own (see its page), and every win also gives 
Isle Fruit to trade at Tobi's stall.
There is no daily limit: the more you farm, the more you gather. Isles battles give 30% of the usual XP, since the Isles are for gathering, not levelling.
Harvest streak
Every win in a row at the same location raises its rewards by 3%, up to +30% after 10 wins. A loss, or running away, halves the streak. It ends when you battle at another Isles location, or after 20 minutes without a battle there.
Bloom
Each day one location is in Bloom, the same for everyone and never the same two days running: it gives +30% rewards and +50% Isle Fruit. The map shows which.
Bonuses add up
The streak, the Bloom and a Harvest Charm are added together, not multiplied. From level 60 (your strongest team Moga), rewards are x0.85, Isle Fruit too (at least one a win). Lucky finds never change.
Tobi's stall
On the Isles, by the Sky Dock. Tobi trades these for Isle Fruit, as many as you can pay for:
| Item | Price (Isle Fruit) |
|---|---|
 EXP Token | 200 |
 Double XP Potion | 80 |
 Evolution Potion | 30 |
The Ancient Ruins also give an EXP Token or a Double XP Potion now and then.
Every win can also leave the location's Cadet or Master card (the Gathering Isles collections).
