By the time the weaving faes arrived, Rino knew the break-even point. He could summon one hundred and two shadow slaves before the mana regeneration could not keep up with his mana consumption. That was a lot more than he expected. Only five shadow slaves were lurking within his shadows to conserve mana, but even so, Rino had more hands than he knew what to do with them.
As it turned out, the more sprites he had under the World Tree's contract, the greater his mana capacity and faster his mana regeneration. It was truly a legendary tree, and that was not all it could do. Through his soul bond with that legendary tree, Rino was now capable of borrowing the different elemental spells his undead body previously could not control. This included his very weak affinity with wind and poor compatibility with light magic.
