Well to anyone that figured out how to get mounted sprites to counter while on your back, it works the same way with owls too. I only happened upon it while goofing around with the owl on my head
I use a counter spam ai with either my sprites or my owl preferably my sprites cause for some reason they rarely get knocked off me with my archer elf and I pretty much can arrow spam everything while I have a walking counter. Counter spam ai and barrier spikes=rare deaths and less hw used for my elf. Other then that I don't find it performs as well with my melee human
