Trial of the Sands

The trial of force is the trial that must be completed in order to obtain the Amulet of Shifting Sands. It was created by the Genine to protect the item.

Location
The Genine ruler, King Kepheres holds the key to the Trial of the Sands. The trial itself is located at the top of Desert Tower. The journeys through the desert are difficult due to the sands and the sandstorms. The sands begin shifting more in the area around the tower making getting to the tower treacherous. This is made worse by the fact that the tower's entrance is 50 or so feet in above the sand. The tower has four support legs that stick into the sand supporting the tower.

Once inside they must climb to the top, the inside contains a spiral staircase that leads up to the top, though whirring, banging, and clanking sounds of mechanisms can be heard in the walls (the tower was originally one of the war machines created during the War of Decreation, but it's original purpose has been long forgotten).

At the top is a door which the key will open, once a creature steps through the door disappears as though it was a mirage. The door will not reappear until the trial has ended.

The Trial
The door leads to a single round room with a 30 ft diameter. The room is incredibly hot and full of sand. It is hard to see more than 5 feet away since the sand in the air obscures vision. Is it also incredibly hot, creatures in the room must make a constitution saving throw every other round (only once the combat begins). On a failure they gain one level of exhaustion. There is a statue of a cat in the center of the room, when it is broken, it turns into a cat which attacks the trial-goer. Regardless of form the cat is immune to exhaustion and the sand does not obscure its vision. At the start of its turn if the cat was killed the previous round, it resurrects as a bigger stronger cat creature until it has been killed a total of 9 times (including the statue, for a total of 8 creatures to fight).
