Guardian Of The Jungle
The moment he sent the old man to send mana to the Mark, his back began to glow with a slight green glow. As the mark began to glow, a surge of energy and strength flowed through the old man's body.
Some of his hair transformed Vines and began to grow from his back. Quickly they began to slither around both of his hands covering it completely. Horns began to grow from his head in the shape of deer antlers. The color of his pupils and hair changed to green.
Even the color of his screen had changed to green, not after this change a small layer of Bark began to grow all over his body. Instead of feet, the bottom of his leg transformed into that of deer-like hooves.
The clothes around his body began to be destroyed as the height of the old man increased by a few centimeters. It is his luck that his entire body is now covered in bark; in turn, he doesn't need any clothes.
