Boost Gem

Boost Gems are the items which are used to your Heroes via the Hero Boost feature.


You acquire Boost Gems by completing a Hero Trial at Level IV (League Level 22) and above, by completing certain event quests or by buying from the Ultimate Tournament Shop. The higher the tier of the Trial, the more Gems you can acquire (max 40/battle).


See the Hero Boost page for information about consuming these Gems.
