Running Assault

Can someone please explain how the “Running Assault” node works for Pathfinder? Specifically the part about not being able to be heavy stunned while sprinting. If you get hit while sprinting do you just keep sprinting or do you get a light stun or something? Thank you.

she keeps sprinting ^^

Just some more details: if you get hit by a projectile while sprinting she just doesnt care and keeps sprinting.
If you run into a pack of mobs she might get stuck due to collision n stuff but no heavy/light stun, you can dodge away with 0 problems.
