I am a GM searching for some means (spell, magic item, artifact, etc) of replicating the power granted by the notorious Infinity Gauntlet as depicted in Marvel's Cinematic Universe. The effect I'm searching for in the game I am going to run as GM isn't "demicide" but is (if anyone recognizes my name and will be in my game spoiler below):
targeting 100% of certain species in the world where my game is set with something like the 6th level spell "Disintegrate".
The 9th Level Spell Wish does not seem to suffice due to this clause in the rules for Wish:
You might be able to achieve something beyond the scope of the above examples. State your wish to the DM as precisely as possible. The DM has great latitude in ruling what occurs in such an instance; the greater the wish, the greater the likelihood that something goes wrong.
I'm looking for something reliable, not a monkey paw that Wish seems to function as when anyone attempts to use it for effects of this scope.
Something that ties into established D&D lore rather than "oh yeah, it's like the movie, but in D&D".
If there is nothing even remotely like the Infinity Gauntlet in any official D&D 5e material, or Unearthed Arcana, then are there any official rules or guidelines on expanding the scope of a spell like Disintegrate to target massively large numbers of targets? I could extrapolate from there.
CLARIFICATION: it doesn't have to have "collect sub-components" as the Infinity Gauntlet needed Infinity Stones to be collected from all over the universe. The important part is if there is already anything or anyone in DnD5e official that has such power.
