Did you read the manuscript just before the pentagram room (and do you have a save before pulling a lever)?
[color:"orange"]In a row, like the water flow, six is thrown, one is not shown...[/color]
Water flows from high ground to low. The 6 levers are all at different heights....
<span class='standouttext'>Spoiler : </span><span class='spoiler'>Pull the levers from highest to lowest and no gargoyles or earth elemental will appear. You will get a little less experience, but much more loot as a secret cellar under the rock in the middle of the pentagram will be revealed.</span>
Some pots and bottles you can sell, otherwise they have no use.
