Another large magic orb came hurtling towards Zhang Yi, who deftly dodged it with his positioning.

Glaring at the undead mage relentlessly attacking him, Zhang Yi, in a fit of rage, pulled out the level 1 iron hammer he had obtained at the train station and hadn't yet dismantled. He charged at the undead mage, dragging the heavy hammer behind him.

Novice gear below level 10 has no class restrictions, so it's not impossible for a mage to wield a hammer.
