Guardian: Ring of warding issue/bug?
I have noticed the same thing
If they have stability they can move through wards. So, make sure that isn’t the case. i have noticed that while my knockback won’t knock foes through the barrier, other knockbacks will.
Sanctuary does not suffer from the issue of rolling through bubbles, but it does suffer from people just walking right into the bubble, and even attacking through it (which seems counter-intuitive. If people could attack through it, it wouldn’t be a bubble, it would just be another ring of warding.
