Best thing to do is just time the spawns when you do manage to find them up. Or you can do astral circuits if you have the spheres timed. The key in making gold is gold/minute, not where you can get the most.

A lot of people say catacombs is the best gold, but they're wrong. It's the best gold in that there are the most mobs there - 50 or so - and thus, at the end of a run, you'll likely have made 15k or so. However, these creatures are dangerous and take a while to kill, not to mention often are found in big groups. It can take me upwards of an hour to finish catacombs, for 15k. Gorgogs + hammerhead shark (hands down the best gold/minute) combo can net about 8-12k, in about 15 minutes.

Here's what I like to do (there is a specific time when to start to ensure astral links):

1. Gorgogs and hammerheads. (note time for respawns) Check krokani, bash if up.
2. Astral, killing only unlinked creatures. At points, you need to wait a minute or two for a sphere to connect - at that time you can link. But, if you have the timing right you can go cancer, scorpio, leo, aries, back to aquarius, then gemini and down.
3. Shallach ur'dead.
4. Catacombs until time on gorgog respawns is up.
5. Rinse, repeat till out of willpower/endurance.

Using this, I can make around 30k an hour, plus good exp and a ton of karma. Argilent, who taught me a bit on astral timing, says his best doing a similar circuit was 52k an hour.

Anyways, the point is...it's all about timing spawns and the essential gold/minute.

Only takes me a few minutes to do the cats when I'm going fast

Warriors bash faster? How?

The Etil'ck quest is awesomesauce.

I actually have an incredibly intricate gorgog-tracking system. It clocks how long it has been since each specific gorgog (identified by IH) has been killed and notifies my when and where they will appear. If I'm on a different plane, my system lets me know a few minutes in advance to head over there. Additionally, it tracks everyone and thirdeye and auto-scries everyone with gems of cloaking to discern if anyone is currently hunting the gorgogs or anywhere near them (based off of the room names). Everyone else who hunts gorgogs is also tracked by the system. It takes their ranking, archytpe, and weapon choice, and with that information, finds their mean killing time for the gorgog. I currently have 76 individuals which I track, all of whom are viewable through a single alias which displays the most up-to-date level, stats, weapon choice, and of course their gorgog killing times.
