Just for cosmetic changes since we’ve been getting a lot of visual effects upgrades in the last patches.
My suggestion is to allow the Illutionist to sell tinctures which automatically convert the colour of your aura to something else. Or makes the aura invisible.
Eg. I’m using Master of Death and Spectral Binding on a Fire based Defiler but would like to see my auras be “orangey” in colour. Similar to what was done with Siphon Souls recently when you convert 100% Vitality damage to Fire.
Having a tincture that makes the auras or even certain toggled skills invisible would also suffice. Eg Maiven’s Sphere etc.
