Shield Maiden Counters
Shield Maiden is almost always positioned front and center as the main tank. Using other tanks with the ability to heal can be a great way to keep her occupied while taking out her supporting Minis. It's also important to try and outlast Shield Maiden compared to dealing a rapid amount of damage. Her Magic Shield can easily take out your team if their attack speed is increased.
Units with the chance to deal a high amount of damage from a single hit or can attack through her shield will be a strong matchup against her. And because of her third ability, Inspiration, you'll want to keep your team from stunning her and take out healers as fast as possible.
