Hey this is a great guide, good work on the research~
I think I have found a permanent window
Quarrel Falls -> Burning Isle GH.
EDIT: After reading a bit more it seems that most windows like this arent permanent, but w/e I can't test atm so someone else go for it if you want
I decided to try this zoning theory out with my small supply of Spiked nogs, this is how i went:
First off, I couldn't find any referance for Burning Isle GH, so I decided to try using another GH in my alliance, Isle of Meditation (as this one is noted as having a limitless window in the first post i beleive).
I went to Quarrel Falls, chugged a Spiked nog and hurried to the GH, nothin happend, travelled to and from a couple times without drinking anymore, still nothin, then I noticed that my counter was going up as it is designed to, every minute.
I didn't really get why it wasn't working (possibly because it's not my GH?), at any rate, I returned to Quarrel, drank one and headed to my GH (Burning Isle).
My minutes went up 3.
I went bak to quarrel and tried again, +3 again, I then drank one while in the GH and travelled back, no effect but I waited to see if the timer would take effect and sure enough it went up +1 after a minute, I returned to the GH and got +2.
After this i decided that drinking in Quarrel and then going to GH and back ~repeat, was my best bet (ie. simplest way, im not out to be the fastest nog chugger out there) and set about finishing off my 25 Spiked's, each one worked without fail and with no timing on my part, I just drank and travelled at random for about 10-15 mins before i ran out. (I also had some normal nogs which worked the same when i drank 5 and then travelled.)
I don't have the riches or the boozes to test this anymore atm but I thought it was worth mentioning as I don't think there is any info on Burning Isle GH or for that matter, using an allies GH (though this is relativley unimportant I think) in this guide/thread.
Keep up the good work to all who got involved
