Half a month later.
During this period, Duke consumed a large amount of Basic Magic Recovery Potions, constantly replenishing his magic power and continuously honing the proficiency of four Earth Magic spells.
With the assistance of the Yellow Sand Crystal, each time he cast an Earth Magic spell, the magic power consumed was greatly reduced, thereby accelerating the progress of grinding proficiency.
The spells Rock Armor, Rock Spike, and Petrification Skin finally reached max level, providing three free attribute points and introducing three new traits.
[Rock Armor: LV5 (Trait: Diamond Hardness)]
[Petrification Skin: LV5 (Trait: Petrification Permanence)]
[Rock Spike: LV5 (Trait: Rock Bomb)]
[Diamond Hardness: Greatly enhances the defensive capability of the Rock Armor you cast]
[Petrification Permanence: Petrification Skin becomes a permanent spell and does not affect the nature of the flesh]
[Rock Bomb: The Rock Spike you cast gains explosive properties]
