I've tested Swiftblade with the following items:
While encountering an enemy hero i used Blade Frenzy and "right-clicked" on the enemy to follow him.
I noticed that while i was near him and he was taking dmg from the Blade Frenzy spin, Swiftblade does an animation of attacking (while spining) and he applied the slow effects to the enemy, WHILE still spinning. I tested it with other attack modifiers after and saw that it works on most. So something like Swiftblade attacking while spinning happens.
Is that intended? how it works?
And a 2nd question. Does Swiftblade's ultimate has intermediate hits based on his attack speed (like Omnislash had in Dota)? Or the dmg here is standar not scaling later on ?
