Sparks of Power are used to upgrade your Heroes' Gift of the Elements in the Guild's Heart of Power. They can be acquired by increasing the power of your Titans, via the following methods:
- Evolving and raising the level of Titans
- Evolving and raising the level of Titan Artifacts
- Raising the level of Titan Skins
- Evolving and raising the level of Elemental Spirits
The higher the evolution and level of the upgrade the more Sparks can be obtained.
Alternatively, they can also be bought in the Titan Soul Shop for Titan Soul Coins. Keeping in mind that 10 Sparks cost 50 Titan Soul Coins without any further discount for buying larger amounts, Sparks are considered as one of the most expensive resources in the game.
