Auras on monsters raised by a friendly Arch-Vile may affect the player.

[argv-minus-one]

In my current game (Hell difficulty, Dark Zone event, in which the Shadows have already arrived), I have a summoned Arch-Vile going around raising friendly monsters for me. This is rather awesome, but for one problem: I noticed one of the monsters it raised had an aura that was stealing EP/ammo/money from me, even though it was friendly. I could see the pop-off numbers indicating which one had the offending aura, too. I killed it, and the stealing stopped, like it would with a hostile monster's aura.
