Global: Good Grief! I'm a Mage, and I Can Modify Skills!

Ling Xiao transmigrates to World of Warcraft.

He discovers that he has just transmigrated and awakened a forbidden class: Blood Mage!

The class deals explosive damage, but every spell costs him some of his own health.

Just when everyone has given up on him, he awakens a System.

He can actually modify his skills!

He changes the cost from his own health to his opponent's health.

His skills have no cooldown, cost nothing, and deal absurd damage!

He becomes invincible just like that!

Goddess: "Oh my god, we're all class-changers. Why are you so strong?"

Everyone: "I'd call him the greatest mage of all time!"

Big Shot: "He's the most brutally powerful damage dealer I've ever seen!"
