Find someone at the Challenger's Promenade who has enhancement potions.
I've conceived a task befitting of your "talents".
Have you heard of the House of Plague? Crafters of toxins and potions. They suffered a tragic accident--a true, true shame.
Herein lies the problem: I have long used the work of the plague devisers to bolster my arena performance. Without a potion of their creation, I'd find the fight unnecessarily taxing.
The brokers do have such potions, but they "do not like my face." Could you obtain such a potion for me?
