In PVE, try to dodge a light attack from a thrall with 1h sword. I haven’t tried it in PVP but you get hit before the animation goes off. I can dodge all the other weapons of thralls personally.
edit: Dodgeable in PVP
edit: This may be because of a connectivity issue. I can dodge the sword fine in singleplayer. Problem in multiplayer.
edit: Added spear, had same problem when thralls heavy attack with spears.
