I don't know how close a fight would be between the two if Xun uses sorcery, if its a 1way win for him, I'd have him not use it. If its still close or straight up not enough, then I'd have him use it. YMMV
Ironhearts? I think.
>The Thrice Cursed Raid of Gorthmogs Lair
The Ironheart fortress dubbed 'Gorthmogs Lair' for its now infamous War Smith Gorthmog Darkbane of the Ironhearts Legion.
He boasted many a time that his fortress was impervious to outside forces, able to withstand any assault, from any aggressor. So much so that various Negator Warbands even took up the challenge, though none ever had the honour of penetrating the outer walls, though one legendary champion did make planet fall.
The Negators were not the only vainglorious Astartes to hear this boast and respond to the challenge.
Strike Captain Ezekiel Titus also took this as an opportunity to have his saga sung for many years to come, and devoted himself to the study of this now infamous fortress.
For decades he planned and plotted, attempting to study its orbital and land based defences, having tracked down and interrogated other Ironhearts to gain what advantage he could.
