I am a wizard! Not a warrior!

Zhang Changsheng, carrying a wizard game panel, transmigrated to a world of swords and magic. Killing monsters allowed him to level up and acquire spells. [You've plundered a first-tier spell from the goblin's bloodline! Stone Throwing!] Zhang Changsheng used Stone Throwing, throwing a punch that shattered the boulder in front of him. "Wait! Dude! A punch that shatters rocks is Stone Throwing?" Stone Throwing = A punch that can shatter rocks; Wind Blade = A swing that creates wind blades; Shield Spell = A body harder than steel, impervious to blades and spears; Healing Spell = Terrifying healing ability, severed hands can grow back instantly; Resurrection Spell = Beat up Death and have Death resurrect you. "I'll say it again! I'm a wizard, not a warrior!" "I curse you goblins to die a miserable death tomorrow!" The goblin leader was terrified, but the goblin sage whispered in his ear, "This wizard is unskilled; he didn't even take the medium for the curse from us." "No medium! How can he cast the curse?" The goblin leader was relieved. The next day, as promised, the wizard, timing it perfectly, broke down the door with his machete.
