Shield
Can someone explain how shields work? I mean if there is an active shield on someone (MM shield e.g.) and I cast another shield e.g. Zelotah, then the amount of shield gets added to the previous one, or it overrides it? And the same with the turn count. If the shield is on 1 turn, and another is cast on top of that, does it gets to 2-3 turns, whatever the new shields duration is?
