What this is
Every Midnight epic gem adds a fixed amount of one secondary stat. A spec's stat weight is the DPS one point of that stat is worth, measured by SimulationCraft on Patch 12.1.0. Rating times weight is the gem's DPS per socket, and ordering the gems by that number is the ranking.
Frequently asked questions
Why not just sim the gems?
One gem is a small slice of your secondary stats, so the DPS gap between two gems is smaller than the sim's run-to-run noise unless you run a huge number of iterations. Stat weights measure the same thing over the whole fight and stay steady from week to week.
Should I mix gems?
Usually no. Stat weights are close to linear over the range a few sockets cover, so the best gem stays the best gem in every socket. Mixing only pays off when two stats are within a couple of percent of each other, and then it barely matters which you pick.
What about meta gems and primary-stat gems?
The ranking covers the single-secondary epic cuts, which is what goes in a normal prismatic socket. A meta socket takes its own gem and should always be filled; primary-stat cuts are not compared here because the weight of a primary stat is not the same kind of number as a secondary weight.
How many sockets do I have?
In Midnight Season 2 a socket can appear on necks and rings from the loot table, and can be added to a head, neck, ring, wrist or belt piece with the seasonal socket item. Count your prismatic sockets on your character sheet and fill each with the top gem here.
How often does it update?
Every Sunday after the weekly SimulationCraft update, when the stat weights are re-simmed. Each spec page shows the SimC build it used.
