Rares and Champions...

[MongoJerry]

I believe this is a full list of possible monster traits: Arcane Enchanted, Avenger, Desecrator, Electrified, Extra Health, Fast, Fire Chains, Frozen, Health Link, Horde, Illusionist, Invulnerable MInions, Jailer, Knockback, Missle Dampening, Molten, Mortar, Nightmarish, Plagued, Shielding, Teleporter, Thorns, Vamperic, Vortex, and Waller.

I was just about to compile such a list. Thank-you. Let's break them down (reply if you know what something does after this message and I'll update it):

Arcane Enchanted: Summons rotating purple laser beams of death. Nasty in combination with crowd control skills like Frozen and Jailor.

Avenger: ?

Desecrator: Creats pools of green poison at players' feet

Electrified: Shoots out small lightning shocks like the lightning enchanted mobs in D2, but they don't seem as dangerous as the ones in D2.

Extra Health: Mob has extra health. How much? Double?

Fast: Mobs are faster than normal. How much? 50% faster?

Fire Chains: Mobs in the pack are linked by chains of fire, which damage players who touch the chain link

Frozen: Mobs toss out ice crystals in the ground that explode a frost nova after 3(?) seconds. Players need to move out of the way or get frozen in place.

Health Link: ?

Horde: ? (Thrall comes to help them?)

Illusionist: Casts a version of Mirror Images. I had a solo champion that spawned four illusions that had a quarter (?) of his own health.

Invulnerable Minions: ? (Have to kill the boss first?)

Jailor: Locks players in place for 3(?) seconds

Knockback: Knocks players back on hit

Missle Dampening: I assume that ranged attacks do less damage. How much less?

Molten: Spawns molten lava on the ground

Mortar: Lobs firey balls at ranged attackers. Get into melee range to prevent this attack.

Nightmarish: Fears players for ? seconds.

Plagued: Creats pools of poison centered on the mob itself. Mostly dangerous to melee characters, who need to move around to stay out of them.

Shielding: Mob can cast a shield that seems to absorb a certain amount of damage.

Teleporter: Mobs teleport randomly

Thorns: Does damage back to an attacker

Vamperic: I assume that the mob leaches life based on damage dealt. How much?

Vortex: Mob pulls a player to them a la a Death Knight's Life Grip in WoW

Waller: Creates walls in random directions and orientations. Can sometimes trap a player in with a mob or get in the way between a caster and the mob.
