what am I doing wrong

So I go hunting for 8 hrs. Totaly different oasis and 90% of the time come up with no cash.

alot of the times it depends on the amount, and what types of troops you hunt with. also, if someone else has recently hunted in the same oasis, or if someone was hunting in the same oasis at the same time.

hunting is one of the most random things that could happen in the game. The thing that makes it impossible to predict is that just because you haven't hunted there doesn't mean that others haven't as well.

cough* hunt where there doesnt appear to be many people, or at least a place un-hunted, cough*

that was a long cough yodac i hope you not ill

my recommendationd for hunting is hunt in the oases you have just resifgned therefore guarentteeing that no onne has hunted in that oases for as long as youve occupied that oasis

My recommendation if you have the time...

Occupy the oasis (and then keep or resign) before hunting. This seems to reset the 'previously hunted' statis. I've been getting 90-95% success doing this. Remember you can send more than one hunt to an oasis at a time.

If you want fast cash, hunt level 9 oasis for 1-4hrs blocks. Resign, recapture, hunt again. Also split troops, if you are vip you should always be sending three hunts out per city.

I didn't say that because you already stated that. I don't need to repeat posts my friend.

infantry also works well, not just cavalry
