A garuda HM light window... kills take 2 1/2 minutes, thats 25 kills (its actually 30 kills an hour but Im being lenient) and hour (so 50 in two hours) and you need to kill her 250 times.
So you can finish light in 5 garuda windows which is the equivalent of 10 hours... Now HAT I can do (wish I woulda come to that realization months ago).. I dunno where ppl got this 40 hours stuff from... that plus I had no clue how fast Garuda drops now... I was expecting a normal party to take at least 5 mins
