Disruption shield (Livid farming spell) blocks ONE attack or ONE special attack (i.e claws), so it'll save you for 1 hit, but if you get hit by teleblock you're still teleblocked, same with entangle and ice barrage (frozen in place), but you won't take any damage for those hit.
Edit: If you log out with Disruption shield, you will still have it, when you log back in.
