A place in the Celestial City where you can use Summoning Spheres to gain Titans. There are 20 Titans in total in Dominion including the 5 Super Titans Araji, Eden, Hyperion, Solaris and Tenebris. The Summoning Circle provides an opportunity to obtain all of their Titan Soul Stones.
Titanite 
[]
Titanite is collected in the Dungeon. Each hero battle grants 1 Titanite and each titan battle grants 5 Titanite. Each time you complete a level for the first time, you gain double the amount of Titanite.
- First clearance of a Hero Battle: 2 Titanite
- First clearance of a Titan Battle: 10 Titanite
Therefore, it's recommended to stop the daily Dungeon on a save point; otherwise, a player must repeat more battles (for the 2nd time) the following day.
Summoning Spheres 
[]
Summoning Spheres are granted if enough Titanite is collected to reach specific goals for either the Daily Quests (3x) or the Guild rewards (15x). Summoning Spheres can also be found in Special Events at the Daily Bonus. A sphere opened can grant 5, 9, or 30 soul stones for regular titans, for supertitans, it will grant 250 soul stones.
