There are a lot of different monsters and bosses in Astellia Roya and many rewards can be claimed by playing dungeons.
The story of Astellia Royal unfolds with main quests, most of which are done in dungeons.
They can be accessed without the related quest, and they are relatively easy to clear.
For this reason, the rewards of scenario dungeon tend not to be very valuable.
Growth Dungeons are unlocked when the character reaches Level 15.
They can be accessed via the Dungeon window at any time from anywhere.
Also, dungeon tickets are necessary to join growth dungeons.
