Well, I am fairly new to the game (never played Heroes), and have played around with a about four or five villians. One of these is a Corrupter and I haven't seen anything on this particular build, so I may try and write my first guide and am taking notes on what I am finding. My Corrupter is a Dark Blaster/Dark Miasma. His origin comes from Magic. Some may call me an idiot, I don't know, but it is working out for me so far.
Major damage dealer and is able to keep himself healed through the fight. At under level 10, I can already take down two orange mobs and a possible one or even two yellows or whites thrown in for good measure.
To take on 2 orange and 2 yellow, I usually have to have some help from healing or endurance enhancements to get through though. Depends on whether my main opening attack hits or not. Working on putting the proper slots and buffs in my slots to be able to hit every time.
So, if all works out and no one else writes up a guide to the D/D Corrupter, then maybe I will give it a shot.
Happy hunting!
