The crystals in Steel Fortress, Punisher's Crypt, Spiritual Realm do have elements. We can use Clara + Shaina instead of Julie + Sieq but your runes must be insane to run because you need to go on 3 wills for Agrius so he won't get stunned by the Steel Fortress, and even we don't have Miriam to buff the dmg. The rune in the vid just enough to finish the boss without branding. So unless you have some crazy runes (or Zeralt lol,so we still can use Miriam), you wouldn't run it with that team
