Okay, the sword throw does have a lot of bugs.
I was just playing around with it, but now this time, if you strike an enemy, and quickly jump on top of him, blood will appear, and the death animation will start, but it would be quickly overwritten by the animation that the enemy plays when you jump on top of them. I wonder if this is caused by an animation overlay or replacement that results in the enemy swordsman living... or it's just that the jumping animation or the [being jumped] animation resets the cooldown to reclaim your blade, so the enemy no longer is being struck by the blade...
Hm, quite intriguing, I'll play around with the sword throw more.
