This isn't the 'Press Esc' method or 'Move quit', or even the 'Stopcasting' one.
I found this out during '07's Love is in the Air event but thought it was common knowledge. At the time you could spam it and the pet would keep summoning and resummoning in the target, doing this as a rogue was hilarious though sadly that part is fixed.
Now, onto the 'exploit':
All you need to do is pick a target, and make sure they are out of your line of sight. This isn't hard to do. For example if someone is on the Org bank roof and you are below it, etc. Just have them targeted and shoot. It will summon a Peddlefeet at their side and you will not lose a single arrow.
I searched this up and couldn't find this exact way to do it, I'm sorry if it's a repost.
Cheers guys.
