Enter stats for two characters and press START. The sim uses the server’s exact damage formula (crit, lifesteal, counter, 2-layer armor). Runs up to 30 rounds, 3s pause between rounds.
Random is based on a build simulator: 5 equipment × 4 lines, each line’s rarity uses the REAL server rates (Common/Rare/Epic/Legendary/Mysthic), plus stats from mount, evolved-mount bonus, evolved-equipment-on-outfit bonus and other power systems. The result is added on top of the default stats. Keep whichever side you like and re-roll the other to find a strong build.
Combat-affecting sub-stats show their %/unit next to the field, like in-game.
