PROFIT
Apes in Banuta: You can go there using only avalanches. Sibangs will loot Coconuts which tend to get very expensive in august due to the Hot Cuisine Quest. I've seen coconuts being sold for up to 10k each one at Luminera. They will also loot Ape fur, which costs more less 8k each one. Last but not least, if you're super lucky you can get a banana staff from merklins. At Luminera, these are valued around 200k each. In average, you will be getting around 4 ape furs per hour plus somewhere between 4 to 10 coconuts.
Magician Quarter - Cultist: These things will drop rope belts, which are used for imbuing mana leech. These are on average 2k each one depending on the server. You can easily loot 20 rope belts per hour.
NO PROFIT
Minotaurs at Oramond: Lots of experience for a lvl 50 here, although it will be most likely an expensive hunt. Take the boat from Thais to Oramond and walk through the glooth pipe. There are higher rank minotaurs that hit pretty hard but they do not have lots of HP so you can kill them easily with sudden deaths. Try to not get away from the stairs 'cause high lvl players usually do not kill them, just pass running through them, and they may lure them accidentally on you. You should get lvl 65 quite fast here.
Issavi Surface: If money isn't a problem for you after you get lvl 65 you can go to Issavi surface North-west and shoot SD on Lamassu and Sphinx while running for your life. (I recommend you 65 because that's the lowest level character I've used to hunt there without being killed. Perhaps it can be done since lvl 50, but I haven't tried it, so 65 is my recommendation). You can get to Issavi from Venore. Once you're there, get down the boat and look for a stair North-west from you. There may be a little crab surrounding the area, and the stairs lead to some kind of pier which you can cross to get to the other side. Cast your magic shield and prepare to run south from the stairs as close as possible to the border until you reach an area with no more than a Sandcrawler. Lamassus will be running to get you and they hit pretty hard so your mission here is to lose them, use Strong Haste. Once you're on the desired spot, it is just a matter of being careful and lure them one by one to the area where you are. Stay as far as possible from them since they hit hard, even at distance. Do not fight more than one at a time. If you do this correctly, you can easily achieve up to 2kk exp/hour just with regular green stamina. Now, I must warn you, this is a quite risky hunt, but even if you die, you can recover lost experience in less than 10 minutes here, so it is always worth giving it a try.
