Titan Soul Stones are required to get titans and to evolve them.
You need 30 Soul Stones to get a regular titan. To summon a supertitan, you need 230 Soul Stones.
You can get Soul Stones of water, fire, and earth titans from:
- the Circle of Summoning;
- Dungeon floors;
- various quests;
- Titan Chests.
Soul Stones of light and dark titans can be obtained during special events devoted to them or from the Circle of Summoning.
If you get a titan that you already own, you will receive 30 Soul Stones for a titan or 230 Soul Stones for a supertitan.
