I was playing with a buddy of mine yesterday and we came across a temple? in the desert, with the 4 chests in the bottom, well not knowing anything I opened one chest and grabbed the contents and then I went to open the next one and next thing you know... yea pretty sure you know what happened... we blew up. Is there a certain way to open these chests?
There was a stone pressure plate under the blue wool. Next time, break one of the orange pieces of wool. Then, you can use a water bucket to get down. Before younger to the bottom, make sure to break the pressure plate.
remember it's a dark room and mobs can spawn down there and set off the pressure plate. so when you come across a desert temple go ahead and get down there to take out the pressure plate.
Sorry but I need help again...
