I guess if Maytag drank a potion for strength and reaction time then that'd work pretty well for close in fighting, presuming she also had two knives on hand. She also had one for invisibility if I recall correctly too. She's a lot better at the anti-magic angle than Bern is, with her ability to resist influencing spells such as fear and a ranged attack which can take out or disable casters. Would have been interesting to see if she could overcome a potion of possession.
Bern could attack if she wanted to, her style is just geared towards defence so if she's up against an opponent who's skilled, she'll need to use that primary style. If she was up against an unarmed caster, I'd imagine she would seek to close the gap quickly and attack. Really, her weakness is against sorcery and that might be undone if she gets the sister sword to the magic one she's got... depending on if it protects against spells and not just magic weapons.
In essence, Sorcerers are really high powered. We've seen them raise shields and still perform ranged attacks so if one does that to you, you're screwed to attack and screwed to defend except dodging, unless its an area affect of some description. The main strategy to pull on a level 3 sorcerer, if you don't have anti-magic, is to wear them out, make them spend their spirit essence and last long enough to see them depleted of it, or pull some disruptive stuff like Maytag did with Dice.
