The shackles of the spell upgrade training were fixed to a certain spell, and the gap between the mage and the aether plane was also small. Although there was also the risk of being contaminated by aether, it was much lower than taking Colin's tobacco addiction.
However, Matthew considered that Rapid Growth was just a magic cantrip and that he needed more training to reach the Tier 5 he wanted, so he simply used the " Rapid Gem " that he had obtained from the traitor of the Alliance, Spencer.
With his current mental strength and the divinity stored in his hands, he should be able to offset the risk of releasing more exposure to the aether plane.
After the preparations were completed, Matthew went straight to work.
The training that matched the spell of rapid growth was, of course, planting trees!
