This is an idea that has been around, but you gave it a good backstory. I'd like to see more of these, because all the other times I've seen this idea it has only been the 4 basic elements. Go to Comment
Good, one thing I'd like to add though is that accidents/natural events can make just as good traps as anything else. And, if the dungeon hasn't been used by anything sentient for ages, then it's almost more likely to have these than an untriggered single-use trap. Methane leaking up though chinks in the walls/floor, a item that is magically electrical falling in a puddle, would both cause a very big boom if the PCs walk in there holding tourches. If it is known that magic enchantments will fade away over he years have a sourceror cast a "half-faded" illusion of a pit over the pit, and under that one have a good illusion of a solid floor. The more ingenious you are, the more realistic the trap becomes, the more the PCs will hate your deviousness, the more they'll understand why not every two-bit punk in the world isn't crawling around these dungeons themselves.

That being siad, maybe, if you are exiled from the order, due to some trangression or another, your book would be burned. The hours you spent scribing the thing wold've been wasted as you watch the well oiled parchment burn. Go to Comment
Yeah, this is basicly a single player (maybe) or an NPC institution. And beyond that 10 years is a good chunk of an advnturer's life. But the death rate isn't all that high if you compare it to the survival rate of adventurers also. Killed by traps, locked up in dungeons never to see the light of day, ect. Go to Comment
I'm American, and do a lot of camping. To 'survive' you need about 2 liters, a gallon has a bit less than 4. In temperate climate you could last about a week off of one of these. However, if you are traveling more than 10 mi(16 km) a day you're going to need more than 2 liters. Thats just from experiance though, I know people who can get by on 3/4 of that, and others that need twice that to keep going. Go to Comment
Good idea, One question though. You said that the owner can see the illusions, but also that to see illusions you needed to know and understand what this tray is/does. Does that mean that the owner needs to know this also or not?
