Juicing Up

Objectives
Find someone at the Challenger's Promenade who has enhancement potions.

Description
I've conceived a task befitting of your "talents".

Have you heard of the House of Plague [sic]? 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?

Rewards
You will receive:
 * 890 XP

Completion
I know Scrapper Minoire sent you. She always enhances herself to win the fight.
