Re: Nameless Knight HELP I cant figure out the tomb puzzle If you look at the tapestry colors it will show you colors of the shields around the room put those in order and you will be bale to open the door. Esmee Cloud~ Promethean Diviner
Any question you have regarding everything in game, look up the subject on Wizard Central Wiki online. You can find every answer you need to anything
Another really great site to check is Duelist101; they have great info on dungeons, bosses, cheats, all you need especially if you are soloing the game or are going to be facing a tough boss for the first time.
The symbols on the shields are of pictures. But I've tried to put them in order but that doesn't open the door
Look at the big tapestry on the wall. Pay particular attention to the bottom of the tapestry. See the colors? You need to choose the color shield around the room that corresponds with the correct color on the tapestry - in the right order (l-r).
Once you pick up the correct color shield, the symbol on it will be what you use on the obelisks.
