At Isle Aphun, your Pokemon will go on 24-hour long missions exploring a cave. After that, they will give you a handful of uncommon or rare items depending on the mission you sent them on.
Different missions will give you different items, and require Isle Aphun to be at different ranks to unlock. Here's all the missions available to you:
|Mission||Isle Level||Item Rewards|
|Path for Odd Shard Hunting!||1||Various colored shards|
|Path for Brilliant Stone Hunting!||2||Various evolution stones|
|Path for Interesting Item Hunting!||2||Any of the missions' rewards|
|Path for Rare Treasure Hunting!||3||Pearls, Gold Nuggets, Bones, etc.|
Path for Odd Shard Hunting! is one of your most (and only) reliable methods by which to "farm" shards to trade for Bottle Caps if you want to Hyper Train your Pokemon (Hyper Training is discussed elsewhere in the guide).
Path for Brilliant Stone Hunting! is how you can find various evolution stones aside from what you can purchase at Konikoni City and the finite supply you pick up in various areas.
Both of these missions as a result are important for you to embark on regularly, in addition to Path for Interesting Item Hunting! which gets you a conglomerate of everything.

High Level Benefits
Increasing Isle Aphun's level doesn't just open up new paths, the higher its level, the more items you'll receive at the end of a successful treasure hunt.
