As one would expect from such a low-level skill, it began to level up quite fast. At some moment, Billy assumed that nothing would happen once some skills reached the level of one thousand. Still, he changed that assumption when he forged some boots using the cores of the monsters and other chromium to protect his legs from the lava and saw them with the skill Heat Immunity.
He probably could do something similar with other skills, but he would need to find the right method and the combinations that made sense. Naturally, he tried to learn that, but it didn't work… the experience was sent to Heat Resistance… tons of it. That was why the skill was level two hundred when he entered the dungeon and now reached the max level.
"Ah… this is better, a lot better," Billy said while the heat was decreasing and the skin of his body was getting less red.
