Multiple tools working together

Everything lives in one place, sharing the same characters, talents, and items.

01.EDITOR

An editor meant for APL

Syntax highlighting, autocomplete, and validation built specifically for SimulationCraft. Edit a rotation, override spell data to test tuning changes, and run the sim without switching windows.

02.TIMELINE

Watch the fight, cast by cast

Every cast is shown on an interactive timeline, complete with buffs and player resources. Examine the sample sequence by itself, or compare it to other runs side by side.

Gear combinations

Gear compare sims the items you have; the optimizer sims the drops you might want.

03.GEAR COMPARE

Sim every upgrade decision

Import everything in your bags, with enchants, gems, and embellishments. Generate missing items from scratch, then find the best combinations between the upgrades you can actually afford (or not).

04.OPTIMIZER

Sim loot before it drops

Seasonal loot from dungeons, raids, and crafting, all in one place. Sim them with one click to immediately find which ones are upgrades for your characters.

05.REPORTS

Clear and detailed results

Run your simulations, compare custom rotations, and share the results. Each report includes all the information you need to understand the sim and make meaningful decisions.

Your whole roster, a few clicks away

All your characters can be easily imported and edited on the fly! Change gear, talents, and consumables without having to leave the app.

Your APL, understood

The editor parses your action list in real time, highlighting conditions, spell references, and variable expressions. Autocomplete knows about buffs, dots, talents, and resources allowing you to focus on the logic, not the syntax.
