Everyone Changes Classes, and This Support Is Pretty Strong

I successfully changed classes, but what the heck are these skills?

Su Mu stared at his status panel, utterly confused:

Ding! Congratulations, Host, you have obtained the skill “Toxic Shadow Skeleton,” which can summon an army of skeletons, beings from another world.

Ding! Congratulations, Host, you have obtained the skill “Venomous Tongue Curse,” which can instantly reduce your opponent's luck to zero.

Congratulations, you have obtained the skill “Endless Smelting,” which can smelt 10,000 ordinary pieces of equipment into a god-tier piece of equipment.

Su Mu: ???

Are these really the skills an auxiliary class is supposed to awaken?
