Well I second this...
If people actually had an aura surrounding them depending on they're god, it'd be much easier to PK them with holy word

...
Bile followers can kinda have a black-ish aura, surrounded by nearly invisible skulls.
Ogma followers can have a sorta toxic cloud around them.
Leucetious followers can have a lightning-ey aura that just randomly strikes them.
The DianChet aura would look alot better if it was redone and made it look more shiny.
The Aengus aura can make everything near the player kinda distorted looking and the player kinda wobble once in a while.
The Balor aura can have the person look like they are constantly on fire.
The Govannon aura can make the player look sorta flowing with power, kinda like going super sayian without the aura and anything else, just the distortion that occurs
