What it does
Forever Sim plays your character through the same fights thousands of times. Every swing, spell, critical hit, dodge and proc is a dice roll, just as in the game, so no two fights go quite the same way. Averaging them shows what a build really does.
Set up one to three builds, press Simulate, and each build plays through every test on the tab you’re on. PvE has leveling against the open world’s mix of beasts, humanoids (some of them casters), undead and more, one, two or three at a time; two tough mobs at once; a dungeon boss with a tank and a party’s buffs; and, for every class that can heal, healing a dungeon, a main tank and at level 60 a raid. PvP has two world PvP ambushes, two open-world fights against one build of each class (one where you strike first, one where they do), and duels between your builds. Everything runs on your own computer; nothing is uploaded.
Two more tabs run bigger jobs. Class rankings puts every build on the site through seven tests, and the healers through the healing tests, and ranks them. Duels pits one build against every other: both start a few yards apart on the same tick, and whoever reacts first strikes first.
Reading the results
- Each test has a row with every build’s result. Open it for the details: a summary, how the build played, one fight step by step, and every number.
- The main build wears the gold dragon ring. The others are measured against it, and its fights are the ones shown first. Any build can be the main build; use its card’s menu.
- “About the same” means the gap between two builds is too small to tell from luck, or smaller than 0.5% (a point, for scores and win rates). Every build faces exactly the same dice rolls, so a clear gap comes from the builds, not luck.
- Ranges hold the true answer about 19 times in 20. Running a test again replays the same dice and gives the same numbers; Precise accuracy runs more fights to narrow the ranges.
Trying a change
Press “Add a build to compare” to copy a build, change something in the copy, and simulate. After you change a build and simulate again, the results say what your change did, measured on the same fights as before.
What it cannot tell you
Talents marked with a grey corner are not simulated yet and change nothing. Everyone moves along one straight line, so there’s no terrain, line of sight or pathing. A few numbers the game does not publish are guesses; you can change them under Settings. The simulated player plays like a typical player: it takes about half a second to react and slips now and then. Switch it to Expert under Settings to see what a build does at its best.
