Aura displays a small poison icon on your temporary enchant frame, letting you know which poison is attached to your weapons, while not obscuring which weapon is equipped. Has support for poisons from 1-60, and shows remaining charges.
You will likely have to adjust size of the auras and spacing of the group to fit your personal display.
In the preview, a Masque skin named Serenity is used to get a circular icon, & custom font named Semplice is used.
