A sim tells you how much damage your character does right now and which gear in your bags would push that number up. It takes about a minute and you don't need to know any theorycraft.
1.Install the Simulationcraft addon
Grab the addon from CurseForge or whichever addon manager you already use (WowUp, CurseForge app). Once it's installed, either restart the game or type
/reloadin chat so it loads.The addon only adds the /simc command and leaves the rest of your UI alone.
2.Type /simc in-game
Log into the character you want to sim and type
/simcin chat. A window opens with a long block of text starting with a line like# DemonHunter "Yourname" "YourRealm". That's your /simc string. It lists your class, spec, gear, talents, stats and consumables in plain text.Click into the text area, press Ctrl+A to select everything, then Ctrl+C to copy. On macOS use Cmd.
Open your bags first if you want Best Gear to see the items inside. The addon only exports what is visible at the moment you run the command.
3.Paste into MythicSim
Open MythicSim and paste the text into the input box on the right. Quick Sim works without an account. Best Gear needs you to sign in (it's free) because it runs hundreds of gear combinations. Signing in also keeps your sim history across devices.
4.Pick a sim type
- Quick Sim
- A straight DPS check on a single target dummy that doesn't move. It's the fastest option, for when you just want to know how hard you hit right now.
- Best Gear
- Tries every item in your bags in turn and ranks them by DPS gain, with set bonuses and stat changes included. Run it after a raid night or a few M+ keys.
- Droptimizer
- Sims the loot from a raid boss or M+ dungeon and shows which ones are worth running this week for your character.
5.Read your result
Results land on a page you can bookmark or share. The DPS at the top is the average across all iterations (more iterations tighten the error margin, and the default is fine for most checks). Below it you get:
- How much of your damage each ability did.
- For Best Gear and Droptimizer, a ranked list of upgrades with the DPS change from each swap.
- A share link you can paste into Discord or guild chat.
Common issues
My /simc window is empty or missing fields.
You ran /simc before logging all the way in, or the addon failed to load. Exit to the character select screen, log back in, and try again. If the window still misses fields, reinstall the addon.
Best Gear says I have no upgrades.
Either nothing in your bags beats what you're wearing, or you ran /simc with your bags closed. Open your bags, run /simc again and paste the new string.
The sim takes a long time.
Best Gear and Droptimizer iterate over many combinations, so they are slower than Quick Sim. For a rough DPS check during gameplay, Quick Sim finishes in under a minute for most specs.
My DPS number seems low compared to parses I have seen.
The parses you see on log sites usually come from groups with extra help like Power Infusion, and often from fights with more than one target. A Quick Sim is one target with standard raid buffs. Compare your upgrades against each other rather than your number against someone's parse.
Once you've copied your /simc string, paste it on the home page and run a Quick Sim.
