Code is taken from master - the only difference is that on One there is no single Sunder Armor Effect spell which only causes the effect. Therefore we need to get the highest Sunder Armor spell from player spell book and cast it on enemy.

The issue I have here though is that it attacks the enemy twice - dealing physical damage twice (once for Devastate and once for triggered Sunder Armor) and also playing the animation twice. Is that blizzlike? Maybe someone more experienced with the spell system and/or warriors at 2.4.3 can take a look at it
