Source & Licences

The engine

BracketSim's simulations are run by a modified version of SimulationCraft, the open-source World of Warcraft simulator. SimulationCraft is free software licensed under the GNU General Public License, version 3, and BracketSim's engine is released under the same licence. You are free to read it, build it, change it and share it under that licence.

Source code of the engine BracketSim runs, with its changes and build instructions: github.com/TheWoWDruidMan/simc (branch bracketsim; what changed and when is in BRACKETSIM.md)

This is not the official SimulationCraft. Please do not report BracketSim results or problems to the SimulationCraft project; they cannot help with changes they did not make. Report them to us instead through Support / Help.

What BracketSim changes

• Old item effects. Procs, on-use effects and chance-on-hit weapons from older expansions that the current engine no longer simulates, restored from the game's own spell data.
• Legacy systems by level. Azerite traits and the Heart of Azeroth (40-50), essences (50), covenants, soulbinds, conduits and runeforge legendaries (60).
• Bracket rules. Level caps on item effects, the group buffs a bracket really has, and the consumables and world buffs each level can use.
• Low-level rotations. Fixes so each spec's rotation keeps working before every ability is learned.

Which item effects are simulated, and why the rest are not, is listed on Special Items. How it all works is in the FAQ.
