Hiya!
For a few years now I've been using my own "special DM helper tables" that I created when we first started learning how to play the "Dominion Rules RPG" (
www.dominionrules.org ; free PDF rules, uses only d12, and is pretty much a Target Number type system). Anyway, I wanted to just keep using only d12. But I wanted a reason to use two or three (flashbacks to Mazes & Monsters, where the Maze Controller, Daniel, gives a little intro-adventure spiel then ends with "Your fate...[opens hands to show 2d12]...is in my hands...let us begin").
Anyway, I created a system I call my "HMC" or "Hot/Medium/Cold" method. Three d12's, one is "Hot" (say, a red or orange colour die), one "Medium" (white, grey, brown), and the last "Cold" (blue, purple, dark green). The tables are laid out so that I roll my HMC dice and simply cross ref. One of the biggest tables is for my "encounter area stuff" (a location the PC's decide to 'look into' or otherwise stay a while). The Hot die indicates the potential level of Treasure. The Medium die gives me the Contents of the area (not treasure!). The Cold die gives me more specifics on the thing that was the Contents focus. So in this way, if I get 3/2/9 (H/M/C), I get: "Low Treasure, Special Contents, Physical Transform is the 'effect' of the Special". Or if I roll 7/11/3, that's "Average Treasure, Beast Contents, Challenging Special". All of these results are nice and loose, letting me fill-in-the-blanks so to speak. Here's the table if anyone is interested in what I'm talking about:

I have used this with 5e (and may other games, actually), and this one table can be easily used with some of my other, more specific, HMC tables (I have them for things like Landscape, Beast Specific Encounters, and others that I haven't put up on the Obsidian Portal site above...just checked; I do have 3 of them up there, actually

).
I did NOT use any sort of 5e rules methods to do this, however. So there are no DC checks on the part of the player to "find treasure". If that is all you were meaning with the OP, then I guess "No" is the answer. I'm not against the idea, just that I would rather have control over the results more so than the Players or Players dice rolls.
