Instructions
Start WoW and enter "/powa" on the keyboard. This brings up the main Power Auras menu.
Select "New" to begin configuring your Polymorph Aura.
Choose your Aura's image from those provided or import your own with "Custom Textures." Select its color by clicking the tiny square button just below the graphical image. Adjust the position and size of the graphic with the appropriate sliders.
Type "Polymorph" in the space provided for the spell name and select "Buff" from the drop-down menu.
Setup the conditions upon which the Aura activates using the options in the Activation tab. Check the red "Enemy Target" box as the spell is used against opponents, and make other selections as you see fit. Complete your Aura with adjustments to how they animate and sound with the corresponding tabs.
