create an ability based off of Sphere in the human abilities
import an attachment or use a current one like an arrow
scroll down into the art section at target art.
it'll say some attachments and the first three will be filled with things like sprite,first, sprite,second, and sprite,thrird
remove all three of those and add in the first one where sprite,first was something like hand,left or hand,right as that is the hand attachment point
go to attachments used or something like that but if im wrong, just keep scrolling down from the attachment point untill you see a 0
change the 0 into a 1
now change the art of it near the attachment point into your desired model.
give your ability to your desired item and when your hero/unit picks it up, he'll have his own personal weapon/item in his hand
