Talk to Thander in the Three Sands Nomad Camp. He will ask you if ever you want to test your blade on tentacles, in the Red Sands Area to the West.

Well unless I have problems with colors and orientation, this might rather happen in Yellow Sands to the East, and it's nothing tremendous: Just fight a bunch of 6 tentacles worth 120 XPs each!

At this time, maybe you will remember one of Brother's "juicy rumors" (Brother, the beggar in Caravan Way, is a very interesting guy actually), relating the taste of Tentacles for Tyrian Slime... So, try to go back there with some Tyrian Slime extract (buy some in Shadow Square) in your inventory! When going through area, you will suddenly feel that tentacles are searching for something in your pack (it's not during a fight, no need to wait for tentacles to appear). If you are the first after midnight, you will be grabbed under. Else you will be released, and nothing more will happen.

If you are grabbed under, you will find yourself in a room where you might have the opportunity to play with some Umber Hulks (the number of them is depending on your level). You can also avoid the fight (see map). When the playing's over, look at a hole in the floor, and jump in. With some minor damage, you will arrive in a bare room with nothing but 4 lever to manipulate...

At the beginning they are all orientated to right, let's say it's position number 0000. If ever you did some mathematics in school, you know that the number of different combinations is 16, from 0000 to 1111.

Actually I wonder if the combination is important, I rather believe it's just random. I suggest you just manipulate levers and after a while, you might get some treasure and Xps... If available, the UNIQUE you will find here are the Sandals of Free Action.

You can also TEAM to go under (up to 4 people, JOIN a leader who has the slime, and all will be "grabbed under"). Each of the adventurers will have the treasure/XPs, even if all 4 are manipulating levers together, as you don't "see" what others do on levers.

Avoiding fight with the Umber Hulks doesn't work all the time, for unknown reasons. So, whatever, be ready for fight, the damn Hulks can make you confused...

Note: According to many players this place should be the beginning of a more important quest, that will perhaps be opened this further game extension.
