How does this work exactly and what is a runner? i ran to temple of london before and it was closed off, couldn't open gate.

well, you need to be able to get in ToL first.
and you need a group of atleast 2.
once he dies the first time, you prd, and the other leaves.
the one that left goes to eastchip, and reparties with you.
once he reparties, you go back into your prd, and he pp's to you.
viola.

I've already killed him once for the quest or what ever it is. Can i get in as many times now as long as i have a second person or do i need to have somebody who needs quest? I was in a party of 3 and they wanted somebody to run there but they were all being dorks, so i ran from the station all the way there and the door was red, not letting me in again.

could have just glitched. its happened to me before, but it eventually let me in. i might have had to prd before it would let me.

Sometimes my doors were red, and i could still run through them. You can still run Abby even tho hes a quest mob. Its not like Wurm i dont think, unless the patch has changed it.

not sure. i'll find out soon as they are done fucking around with the new 1.3 patch. heh, why can't they do this shit while i'm at work.
