To use Mythic Sim in WoW Forever, install version 0.3.0 or newer of the MythicSim addon, generate a character string with /msim, and paste the JSON data directly into the Forever simulator page. The resulting DPS numbers come from a beta sim of your own exported character against a raid boss with full raid buffs and consumables but no world buffs. Because reference builds and engine rules are evolving through testing, these figures serve as a baseline comparison rather than an exact prediction of live performance.
How to Export and Run a Simulation
Running a character simulation in World of Warcraft: Forever uses a dedicated data string rather than the formatting found in modern retail clients.
- Download and install the MythicSim addon, ensuring it is version 0.3.0 or higher.
- Log into the game on your character, then open the export window by clicking the minimap icon or typing
/msiminto the chat box. - Copy the generated JSON text from the window.
- Open the Forever simulator page, paste the text into Quick Sim or Best Gear, and run the calculation.
Standard /simc strings from retail expansions cannot be used for Mythic Sim in WoW Forever, as retail SimulationCraft does not model Classic-based combat rules.
Combat Engine and Forever Mechanics
MythicSim evaluates Forever using a customized fork of the open-source wowsims Classic engine rather than SimulationCraft. Because Forever functions as Blizzard's Classic+ project at the level 60 cap, the platform adapts 1.12 combat rules to incorporate six major system reworks:
- Unified hit: Melee, ranged, and spell hit share a single stat, valuing accuracy gear equally across archetypes.
- Unified crit: Physical and magical critical strike ratings combine into one universal stat.
- Expertise: Dodge and parry reduction is an independent stat, replacing legacy weapon skill racials.
- Spell damage from healing: Bonus healing provides spell damage, creating crossover gear between damage and restoration specs.
- Periodic crits: Damage over time abilities can score critical hits, directly boosting bleed and Affliction builds.
- Reworked racials: Weapon skill passives are eliminated, and racial abilities are distinct across all races.
Development also includes an experimental Rust-based engine designed to mirror the production Go engine across all 29 spec builds. An engine match merely proves identical output to the reference code rather than parity with live servers.
Encounter Rules and Reference Builds
Each saved ranking board sims a fixed reference character under standard conditions. A saved board runs a fixed level 60 reference setup against a single raid-boss target for two minutes. Characters operate with full raid buffs and standard consumables, but without world buffs.
| Rule Setting | Simulation Standard |
| Target Level | Level 63 raid boss |
| Fight Length | 2 minutes |
| External Buffs | Full raid buffs, zero world buffs |
| Trinket Slots | Empty on the spec's trinket board baseline, best pair on the tier list |
The talent setups used on these boards are subject to ongoing refinement. "Nah, the talent builds this simulation uses are not good." observed one player regarding the default setups.
How Much to Trust the DPS Numbers
Simulator outputs must be approached with caution during the testing phase. The database models the BlizzCon demo and patch updates, but loot tables for new instances such as The Barrow Deeps and Hyjal Summit remain unreleased, preventing true Droptimizer modeling. These sims run ahead of full gear clarity, an issue many players consider a reason the numbers remain premature.
Talents and mechanics shift frequently between beta builds, altering spec outputs on updated engine revisions. Players interested in optimizing form management can consult our WoW Forever Feral Druid Changes guide to see how specific updates impact mechanical balance. Treat the tier list ranks as comparative models of baseline talent interactions rather than definitive statements on live viability.
