Frequently asked questions

What is the best gem for Affliction Warlock in Patch 12.1.0.69933?

Flawless Deadly Garnet (+Critical Strike) is worth 690 DPS per socket for Affliction Warlock on single target, the most of any epic gem, so it goes in every prismatic socket.

What is the full gem order for Affliction?

Flawless Deadly Garnet (+690), Flawless Versatile Lapis (+655), Flawless Quick Peridot (+606), Flawless Masterful Amethyst (+565). The number is DPS per socket from the spec's stat weights.

How many sockets do I have?

Check your character sheet: necks and rings can come with a socket, and the seasonal socket item adds one to a head, neck, ring, wrist or belt piece. Fill every prismatic socket with the top gem here and the meta socket with a meta gem.

Should I mix gems?

No. Stat weights are close to linear over a few sockets' worth of rating, so Flawless Deadly Garnet stays the best choice in every socket. Mixing only matters when two stats are within a couple of percent, and then either is fine.

Why is this derived from stat weights instead of simmed?

Swapping one gem changes DPS by less than the sim's run-to-run noise, even at high iteration counts. Stat weights measure the value of each stat over the whole fight and stay steady from week to week.

How often is this updated?

Every Sunday after the weekly SimulationCraft update, when the stat weights are re-simmed.
