Water Essence is one of the game's resources. It is the harvested essence of water, used to upgrade magic skills.
It is obtained through
- Battles and Level Taxes on Lava Plains, plus the final and bonus scenarios of The Tundra
- Supply Station
- Reward Center (Daily Check)
- Daily Login Reward (random)
It is used to upgrade magic skills on the Magic Ward from level 21 until level 51. There are two areas in Lava Plains that do not have the potential to provide Water Essence, Scorched Waste and Flaming Plains.
It can be Synthesized into Pure Water Essence at the Forge. You need to level up a magic skill of any kind to level 51 before you're able to do this. After all your magic skills are at level 51 or more, this is the only use left for this item.
The max stack of Water Essences is 9999.
