Mordel is a typo, its model guys. Anyway. There are some tutorials on weapon removal in the tutorial section. Read and follow them. Is that too much work or too hard? use the villager model.
Then you must download a attachment from here. Search for a weapon and download it. Then import it into World Editor.
Now make a new ability based on sphere(You can use triggers to attacj but it gives problems on death I thought). Change the attached model to your imported file, and change the attachment point to right hand or left hand. If you dont fully understand read a tutorial
