It isn't the first Duel Arcane in Faith's life, and she's sure not the last either. As so, she isn't going to gawk at the duelists as if she was some vanilla Initiate fresh from the Supernal Realms.
No, no, she's gonna watch attentively to the details. The Clash of Wills could be almost felt under skin with two Masters; their Swords and Shields of choice, as seen with her eyes open wide, spoke of their minds. The sheer power of the fight makes her shiver.
Subtle, yet brutal. Enlightened violence.
Through Faith's head flies the thought:
I need to get at least as powerful as them to make my goal true.
The Theurge shivers again and looks around. No time for this, better watch if nobody's trying to cheat...
