New Aura Ideas

I was just casually discussing the aura system people while playing PoE last night and was kinda 'inhibited' lets just say... Alright let's face it I was hammered and we came up with some interesting concepts for some Auras I run by the community and see what you guys think now that I am sober enough to type.

1. Aura - Time Bomb
this aura would have no effect on the rare monster that spawns with it. The idea of this aura is that all the monsters effected by it would explode either when killed or after a certain amount of hp is taken off dealing damage not only to you but to all other monsters around them that could set off a chain reaction with epic and potentially catastrophic proportions!

like so:



2. Aura - Berserk
I think this aura really has some potential to it. The monster which is effected by this particular aura when brought to low life would go into 'berserk mode' increasing there defenses, speed and attack power all at the same time (proportionally to the other auras of course) any other monster would then be effected by this berserk state as well sending them into the same state.

i imagine the monsters growing in size slightly and turning red to symbolize their state
like so:



3. Aura - Blood Idol
This one might be a bit of a stretch as far of mechanics ago, but it can't hurt to suggest it. This one mainly has to do with a roulette kind of mechanic. The rare spawning with it would be invincible and a greenish-gold type aura would surround him. Now the monsters effected by it would get the aura as well however, the actual 'Main Aura Graphic' would randomly appear on a nearby monster every couple of seconds and the only way to kill the invincible rare would be to kill the monster with the 'Main Aura Graphic' (or whatever beacon chosen) would kill that monster and said invincible rare at the same time.

Anyways any feedback or criticism would be great. *cheers* - Z

P.S sorry for the wall of text
