Jade in ANW
When they arrived at the next site, Solvi quickly found the best location after inspecting the grounds. Sofiera then started the construction and Eldrian added his mana to hers.
After some experiments, Eldrian found he could move his mana according to another's spells and will. It was the reverse of his mage battery plan, but it still worked. Adding his mana to more competent people wasn't a bad turn, either.
Solvi then took control to harden the dirt once Sofiera finished. Enchanting it to turn it from simple dirt into a type of magical compound. Near the end, the first wall of the second floor was finished. Hard enough to take even a number of Eldrian's full powered punches.
Crystoi, however, would tear through it with ease. So naturally, he hadn't used it when testing the sturdiness of the first walls.
