Determination

Upgrading a spell, as the name suggests, was to upgrade the spell in all directions, open the core of the spell model, replace the rune arrangement, character combination, rune formula, and so on, and replace the previous low-level runes with higher-level runes so that it could bear more powerful energy and produce greater power.

This was not a difficult task, but it was not easy either. Everything depended on the level of knowledge of the Wizard themselves.

If they had enough knowledge and enough understanding of runes, it would be easy to do this job. One day, one hour, or even a few minutes, they could complete the upgrade of a spell model.

But if they did not have enough knowledge, then they could not upgrade.

Heath belonged to the former.

Soon, the first spell, Half-Life Soul, had been upgraded by Heath.
