A /simc string is a plain-text export of your World of Warcraft character. The Simulationcraft addon generates it when you type /simc in game. It lists your class, spec, talents, equipped gear and the gear in your bags, which is what a simulator needs to model your damage.
Anatomy of the export
It looks dense in a text editor, but the shape is simple. These are the lines that matter:
# Frostfire "Yourname" "Your-Realm"- A comment header for humans: class, character, and realm. Lines starting with # are ignored by the engine.
mage=yourname- Declares the class and names the profile. This is the first line the sim engine actually reads.
spec=frost / talents=C8DAAA...- Your active spec and the full talent loadout, encoded in the same string format the in-game talent UI imports and exports.
head=,id=212345,bonus_id=6652/10355,gem_id=213743- One line per equipped slot. Items are referenced by ID with bonus IDs (item level, tertiary stats) plus gems and enchants, enough to reconstruct the exact piece.
### Gear from Bags- Below this marker, every gear item in your bags, commented out. Best Gear and Droptimizer sims read these as swap candidates.
That bag section is why opening your bags before running /simc matters: it is the candidate pool that a Best Gear sim ranks and that a Droptimizer compares drops against.
What it does not contain
The addon builds the export from what the game client knows about your character. Your account login, email, payment details and session tokens aren't in it. Sharing a /simc string is about the same as linking your armory profile with your bag contents added.
Generating and using one
Install the Simulationcraft addon, type /simc, copy, and paste into MythicSim. The full step-by-step, including troubleshooting for empty exports, is in the how-to-sim walkthrough.
Frequently asked questions
Is it safe to paste my /simc string into a website?
Yes. It describes your character's gear, talents, stats and bag items in plain text. Nothing in it can be used to get into your account. The only personal details are your character name and realm.
How do I get a /simc string?
Install the Simulationcraft addon, log into the character you want to sim and type /simc in chat. Copy the text from the window that opens and paste it into your sim tool.
Why does my /simc string miss items from my bags?
The addon exports what the client can see when you run the command. Open your bags first, then run /simc again. Items in your bank or void storage are not included unless the bank window is open.
Do I need to update my /simc string after changing gear or talents?
Yes. The string is a snapshot taken the moment you run /simc. Any gear swap, talent change, or enchant applied afterwards is not in it, so re-export before each sim session.
Does the /simc string work with any sim tool?
Yes. SimulationCraft defines the format, so the same export works in MythicSim, Raidbots or a local SimulationCraft install.
Paste your /simc string on the home page. A Quick Sim takes about a minute and doesn't need an account.
