Help with Gwyndolin (SOLVED)

Hello people. Gwyn and Gwyndolin are the last remaining bosses in my game, and the latter represents the bigger problem; I'm using a Pyro/Melee build under 50% and I can't get to close the distance. I'm on PSN (Ahzran-) and I'm LVL83.

I'd appreciate if someone would be interested on helping me. I don't mind if you want an item in return , just let me check if I actually have it.
My timezone is GMT-3, by the way.

EDIT: D'oh. Totally forgot.

May we have a soul level and system please

Totally forgot about that. Fixed.

I got a character that is at sl70, would that work? I can't do it until either tomorrow morning or evening.

Sure, no worries. I'll let you specify the time, since you are the one who's helping.

The thing is, I'm not sure when I will get access to the console . How about you add me and we can see if were online together sometime. If we don't manage it, then I hope that someone else responds to help too .

Dont know if you know but even after he teleports you can still hit him. Theres one or 2 seconds after his body disappears that you can attack that light he leaves behind and hurt him. Use a running attack (not pyromancy, takes too long) and you'll eventually kill him.

YES, it worked. Thanks for the tip, DoughGuy, and thanks for the interest Berkut. I'm solidly into NG+ now!

Congrats!
