Lower DC this time than last - an adaptation of a classic puzzle. You and your travelling companions are exploring a tomb somewhere on Dregar. The party's rogue, while searching for traps, stumbles across a hidden door to a chamber hitherto unexplored. It is only after you and one other party member step through the newly opened door that you discover WHY no one ever reported the room's existence - a heavy stone slab slams down, a secondary door, sealing the room. You turn and smite the rock with your sword, to no avail - the glimmer of protective enchantments ward the stone against any sort of harm, physical or magical. As your companion crosses the threshold into the room proper, there is a low hum and the eerie whine of a spelltrap activating, and the green glow of a feeblemind spell outlines your hapless companion for a moment. A hurled dagger destroys the source, but it's too late: without any readily available cure, your companion is now essentially mindless - capable of obeying commands, and not much else. Growing ever more concerned, you spy a plaque on the wall, and three containers sitting below it, as well as two tables with raised circles - likely pressure plates - in the centre of the room. The largest of the containers appears to be full of diamond dust. The plaque reads as follows: Heed my words, intruders all Or those who seek to raid my hall Thy fate is sealed, entombed forever Unless thou art both quick and clever Sitting right in front of thee Exist the tools to set thee free Place two urns of equal weights Upon the tables' trigger plates But 'ware, if thou should place them ill Thy stone-walled tomb with gas will fill And chok'd to death, thou shalt await For company to join thy fate In plainer text, I shall explain: The urns are of equal weight, but varying capacities - the largest can hold eight pounds of dust, the smallest three, and the middle vessel five. Mind thou dost not spill - my mechanism, ancient or no, is quite sensitive. Let this be a lesson to thee whether thou escapest or not - do not meddle in the tombs of thy betters. Oh, and as a final thought - the urns themselves are of insufficient weight to trigger my mechanism, and every ounce of the diamond dust will be required to make the door yield passage once more.
So, left entombed but with a hope - if you can only figure out how to place equal weights of dust on the two pressure plates, you can escape. But if you get it wrong, you and your mindless companion are doomed. Can you make it out alive? //PM me with your solutions, as before! // 5 minutes or less (unless you already know the solution) == DC 16 // 5-10 minutes == DC 14 // 10-20 minutes == DC 12 // >20 minutes = DC (2 / (time required - 19)) + 10
