Chapter 579: The Sevenfold Rainbow VII

Bzzt!

A lightning arc appeared beneath Grimm's feet. Grimm went deeper into the direction of the ancient rainbow light.

Grimm's mental strength was reduced from 196 points to 162 points, a reduction of thirty points. Now, Grimm could only use one-sixth of his mental strength, 27 points to be exact.

Thus, Grimm's destruction spell that could previously deal 4,500 points worth of damage had now been dropped to 3,500 points. It was quite a stark difference.

If Grimm were to trigger another round of Immortal Body, he would no longer pose any threat to an ordinary Level-3 creature. Moreover, any ancient Level-3 creature could easily finish him off.

Therefore, as mystical as the Nightmare Sorcerers were, they were not invincible.
