A wall of wind slammed into his body, blowing the Overlord off of his feet and into the air. This was certainly unfortunate, usually his armor weighs more than enough to keep him firmly planted on the ground. This must have been at least as strong as a Hurricanes' eye wall, or maybe even a tornado. Whatever the strength was, it didn't really matter, it was sufficient enough to be a problem. 

As he flipped through the air, he noticed that there was in fact a second projectile being sent his way. "Bother." Was all he managed to get out before it slammed into his chest. Punching a jagged and messy hole through his armor, crushing his ribcage and what remained of his internal organs. A putrid brown sludge leaked out through his armor and onto the ground, soaking the earth in his filthy rotted body and blood. 

Quickly meeting them on the ground, the Overlord writhed and howled. Pain was still quite noticeable, but, not enough to kill him. (Admittedly, the only reason I chose to let him survive was because you wrote it vaguely. Rather than specifically targeting his head. Remember. He's both a Lich and a Zombie.) 

The Overlord's body was convulsing on the ground, stewing in his own pain and frustrations. "You know! I'm growing increasingly angry at your incompetence! I now have to feel this pain! Do you understand just how painful it is to reconstruct a skeletal structure!?"
