Using Skill Tree Boosts

Beat the Skill Tree Quest

To unlock a Hero's Skill Tree, you first need to "Bloom" them and complete their Skill Tree Quest. Once the quest is complete, one of their skills will be improved and their "Skill Tree Quests" will be unlocked.
You can access the Skill Tree or its quest by selecting "Skill Tree Boost."

You can access the Skill Tree or its quest by selecting "Skill Tree Boost" from the Training menu.
Only Heroes that have gained Skill Trees and been Bloomed may be selected to challenge Skill Tree Quests.
Details on which skill improvement you will gain from clearing a Skill Tree Quest are available before you challenge it.
During a Skill Tree Quest, you must include the relevant character in your formation. You may use any other Heroes or Sidekicks you like.

Going Down the Skill Tree

After clearing a character's Skill Tree Quest, you will be able to access their "Skill Tree Boost."
There you can acquire Skill Panels that will upgrade the Hero's individual skills.
Each Hero requires different items to acquire Skill Panels.*The amount of items you need depends on the amount of Skill Panels you have unlocked.

As you use items and acquire Skill Panels, the number of "unlocked panels" will continue to increase.
Regardless if Skill Panels are later removed.
The total number of Skill Panels you are able to acquire is limited to the number you have unlocked.

*
Powerstones required to unlock Skill Panels can either be bought at the store or acquired from Livos/Rank Up Item Quests found under Training/Growth Quests.
If you don't have enough livos to buy them at the store,you can gain more from quests or Sales!

Filling out a character's Skill Tree can greatly improve their skills!

For each skill, Skill Panels can be acquired in order starting from the top.
Skill Panels with two branches allow you to acquire panels on both sides.
You can acquire a new panel by acquiring all of the Skill Panels above it.
You are able to remove Skill Panels you have acquired. Removing a panel enables you to acquire another available panel without using more items.
