+Res -Def H!Myrrh thoughts?

You didn't really have to repost the same question in such a short time frame, but she'll still do fine against some non-armored units when it comes to the def comparison. Just give her an A-skill that maxes out her defense somehow if you want to utilize her weapon effect. Even the most budget friendly options like armored blow 3 work here.

You can also always replace her weapon for lightning breath or whichever other breath you want.
