This Shield is extremely redundant if you already have an Electric pet, but otherwise it’s still situationally useful.
-Can be used as an alternate rushing style in dungeons like Abyss or Deadwater Docks (but will sometimes underperform compared to a tiered Shield, for example in Tomb where the ability to silence Turrets and Archers is invaluable).
-Decent Shield for Mundane runs when you don’t have spare Ogmurs lying around.
-Can be used to great effect when there are already several Knights taking care of the Stun or when keeping the boss in place is more important than trying to prevent it to shoot (best example being the two Mad Lab bosses).
