I'm a Lightning Psycho, all chars level 30 with final equipment, and there is no way at all that it is possible to defeat the Corruptor. I have absolutely no way of dealing more than 10000 damage, the most I can deal is ~7000 with Shock Therapy. I even tried stun-locking the Corruptor for 99 turns, but she just recast it. Damn.
My question is, is it even possible, or do I need a Speed Bio?
The problem with the corruptor is that, after one orb is destroyed, he turns almost invincible, so the best we can do is kill him without destroying the orbs.
Put 3 points on Shock Coma and put it 2 times on your action bar, and use it to stun the orb that damages itself and it will recover enough health to prevent it from dying. Now damage the corruptor like there's no tomorrow, making sure you keep the flawly designed orb comatose. You will have to deal a lot of damage to counter the healing it may receive from the other orb, but with time it's possible. Once the corruptor dies, the battle ends.
old thread, i know, but as a psycho, just go with the one-shot build.
3/3 shock coma 4/4 high voltage 1/1 overdrive 2/2 retrograde
high voltage > high voltage > shock coma > shock coma > high voltage > retrograde
the damage is based on percentage, so it always works unless veradux(idiot) dispels a high voltage. this way u can put all ur attribute points in speed or vitality since str and ins don't effect it. happy one-shotting
