Later in game you can just buy them from a few vendors, but at this point on Green, you'll need to either buy one or farm one out of Befallen. Toss it in the bank, it's a nice bit of peace of mind.
If /corpse hotkey doesn't do it, then shake a tree and watch all the necros fall out and ask one, and as last resort, go to the bank and retrieve this rod and use it yourself.
