Hit Poison Area

Galluccio

Does this mean everything in the area gets poisoned?

No the enemies in the area are hit with poison damage, but are not poisoned. 

Galluccio

Is it a type of AOE attack?  IF so, what is the range, how many enemies can it damage, and is there a cap to the damage?  Is this a must have spawn property?

May be physical, fire, cold, poison or energy type. Has a percentage chance on each hit to inflict damage on all hostile creatures within a 5 tile range of the initial target instead of the main target. Will hit hidden targets.

If you are talking about champ spawns then yes, hit x area is important. Bring the correct x area and slayers. That's how you see melee mowing down massive groups, hit area and whirlwind.
