Medivh was currently a Tier 3 Mage. He could resurrect low-grade skeletons quickly, but the Spring of Time they produced did almost nothing to improve his mental power.
To maintain his rate of mental power growth, it was best to resurrect the highest-grade skeletons he could currently manage: Yellow-Grade Skeletons.
Purple-Grade Skeletons were the next best for cultivation, while Blue-Grade Skeletons were mainly used to temper mental power before advancing.
After keeping the Skeleton Assembly Line running for a month, Medivh returned to his previous resurrection strategy. Each day, he resurrected one or two Yellow-Grade Skeletons for meditation, then tempered Bone Power to upgrade his Bone Source Equipment and Bone Spirit Substitute.
If he had any spare time, he would also resurrect some Grey Bone, White Bone, and Green Bone Skeletons.
Once the Bone Spirit Substitute advanced to a Blue Bone Skeleton, he would leave the production of all low-grade skeletons to it.
While Medivh was busy resurrecting skeletons and cultivating, the Skeleton Mage Corps conducted research in various fields.
In Storm City, the Elemental Skeleton Mages had cultivated many magical fruit trees after repeated rounds of selection.
Medivh named the magical fruit trees according to their elemental affinities: Earth Spirit Tree, Ice Spirit Tree, Fire Spirit Tree, Wind Spirit Tree, and Magma Spirit Tree.
The first four were magical fruit trees with a single elemental affinity. The Magma Spirit Tree was the only one with mixed elemental affinities, perfectly balancing fire and earth.
In the field of Potions, the Potion Skeleton Mages and the Spirit Fox Warlocks, who specialized in potions, used five kinds of elemental fruits, Fire Spirit Wheat, and other magical materials to develop various potions.
Some potions were used for cultivation, some for healing or killing enemies, and others had unusual effects.
