Chapter 636-intense battle (3)

The corrosion spell was a spell commonly used by Black Mages. This spell could be said to be very powerful, but it was not very impressive if it was not powerful. It mainly depended on the poison used by the Black Mage who used the corrosion.

The reason why the corrosion spell had such a result was that it was a growth-type spell. Magic was divided into low-level magic, high-level magic, and forbidden magic. Among these magic spells, there was also a growth-type spell.

The growth spell was a spell that could be slowly upgraded, just like the corrosion spell. The corrosion spell was a very special spell. When practicing this spell, the mage had to find a poison and slowly refine it with magic. The next time he used the corrosion spell, the poison would be in the spell.

When the mage's level was higher, he could refine stronger toxins, which would be equivalent to an upgrade in the spell. The more toxins he refined, the more powerful the spell would be.
