When using a Ward of Dawn with Helm of St14, it gives you Armour of Light while inside the bubble and Void Overshield (10 seconds). However, the Void Overshield does not refresh while inside the bubble, like it does for a Bastion Barricade. It counts down while inside, so if you want to refresh Void Overshield from bubble, you have to go out and dip back in. I assume this isn't intended.
