Thanks for your response 
I’d prefer not to buy anything from the marketplace yet^^
And yes I’m tracing from several places on the sword from last frame to the current frame, but I think the hitbox attached to the sword is the problem.
It seems like the position of the blocking sword isn’t updated. If I hit the location where the sword is in idle and/or the arm that is holding the sword, I get a collision with the enemy sword even though it is over the enemys head according to what I see. So the visual and the actual positions are not in sync.
