How to use it
What each part of the site does, how to fill it in from a battle report, and how to read what comes back.
Quick start
Pick the battle type
City attack, rally, garrison, duel and so on. It decides which exclusive gear skills count and how losses split into injured and dead.
Fill in both sides
Load a saved report, read one from your screenshots, or type in troops, stat bonuses and heroes for each side.
Press Simulate
The fight is played hundreds of times. You get the win chance, the typical losses with a likely range, and the turn-by-turn story.
New here? Try a real battle: it fills in a real duel from the Alliance Championship so you can see what goes where, then press Simulate.
Setup
- Battle type
- Where the fight happens. It changes which exclusive gear skills count (see the table below) and, in events with no deaths, how the losses are shown.
- Load a battle report
- Real reports, already filled in. Pick one to see a complete setup, or to check a fight you remember.
- Import from screenshots
- Take screenshots of your battle report (overview, stat bonuses and the troops page) and the simulator reads them. The pictures are read on your device and never uploaded. Check the numbers before you simulate.
- Past battles
- Every battle you simulate is kept with its result. Open one to see that result again and put its setup back in the form, without using a simulation. Signed in, your newest 50 are kept with your account on every device; otherwise the newest 20 stay in this browser.
- Heroes
- The three heroes leading the march, one per troop type. Their skills are rolled in every simulated battle.
- Joiners
- For rallies and garrisons, add each joiner's first hero. As in the game, the four highest-level first skills count.
- Troops
- One row per tier and Fire Crystal level. For a rally or garrison, add every player's troops; one row per tier and Fire Crystal level is enough.
- Stat bonuses
- Copy the twelve numbers from the report's Stat Bonuses panel: attack, defense, lethality and health for each troop type. They already include research, gear, pets, gem buffs and exclusive gear skills, so don't add those again.
- T12 troop skill levels
- Only for T12 troops: the level of each troop type's T12 skill, 0 to 24.
- Buffs
- Battle-pet skills and gem buffs for armies you entered without them, such as your own saved army. Set the levels once, then the Pets and Gem buffs buttons switch them on and off with one click. Leave them off for a side copied from a report: its stat bonuses already include them. In duels the game always applies pet skills, so they count there even when switched off.
- Actual losses
- Optional. Add up the report's injured, lightly injured and lost troops for each side to see whether the real fight was lucky.
Result
- Win chance
- How often each side won across the simulated battles. A close fight (under 70%) can go either way; run it with more battles before you rely on it.
- Expected losses and range
- The typical loss for each troop type, with an 80% range: eight in ten simulated battles ended inside it. The game has luck in it, so read the range, not just the middle number.
- Battle power
- One number for each side, so you can compare two armies at a glance. The higher number usually wins; when the two are within 10% of each other it is too close to call, and the simulation is the better guide.
- Luck
- With the report's actual losses filled in, it shows where the real fight sits among the simulated ones: lucky, as expected, or unlucky.
- Turn by turn
- One average battle, turn by turn, so you can see which troop type falls first.
- Skill triggers
- How often each hero skill fired on average, and the troops its extra damage killed.
- Share
- Send a link or a picture of the result to your alliance chat. A link opens the same setup; it doesn't run until someone presses Simulate.
Improve
- Hero Advisor Pro
- Keeps the other side exactly as entered and tries other hero sets for your side, using only heroes your server has unlocked. Set how built up the suggested heroes and their exclusive gear are.
- Troop Ratio Advisor Free account
- Every infantry, lancer and marksman split of the same troops, so you can see where your mix sits and which way to move it.
- Next Hero Advisor Pro
- Ranks the three heroes of a season you don't have yet by how much battle power each would add to your army, for a rally attack, for defending a city or garrison and for a duel, so you know which one to save for.
- Stat Upgrade Advisor Pro
- Ranks your 12 troop stats by how much 10 more points of each would help your army, against the enemy you entered or in general. It also scores which troop type gains the most from upgrades that raise two stats together, such as chief gear and chief charms, so you know where your next upgrade should go.
Rally chain
Line up several rallies against one garrison, in landing order. It shows how many it takes to break the garrison and how reliably, with the refill between rallies taken into account. Pro also finds the best order to send them.
Rally timing
Give every rally leader a start time and a live countdown, so rallies from players at different distances all land in the same second. Share it as a link or paste it into game chat. It's free for everyone.
Exclusive gear in each kind of battle
A hero's exclusive gear skill (players often call it the widget) adds 5% to 15% to one stat for all your troops, but only in the right situation. Rally gear works for a rally leader, defender gear works for whoever holds a city or garrison, and neither works in a solo attack or a duel.
When you copy stat bonuses from a report, the exclusive gear is already in them. The simulator only puts exclusive gear on or takes it off when the Improve tab swaps a hero.
| Battle type | Attacking | Defending |
|---|---|---|
| City attack, SvS, Foundry, Frost Dragon Tyrant | Rally gear, when it's a rally (with joiners). None for a solo attack. | Defender gear |
| Duel (Alliance Championship or Expedition Arena)One on one; troops are only injured | None | None |
| Wild Brawl, gathering tile | None | None |
| Gaia Heart, Labyrinth | None | None |
Only one set of stat bonuses counts for each side: the rally leader's, or the garrison's bonus source. Joiners add their troops and their first hero's skill, not their stats.
Questions
Why does the win chance move when I press Simulate again?
Each press runs a fresh set of battles with the skills rolled again, the same luck the game has. With 200 battles it can move by a point or two; run more battles for steadier numbers.
Are Alliance Championship duels and Expedition Arena fights the same?
For the simulator, yes. Both are one-on-one with troops only injured and no exclusive gear skills, so both go under the Duel battle type. What differs is the exclusive gear: a hero whose exclusive gear helps in rallies or garrisons gets nothing from it in a duel.
Should I add my pet or gem buffs to the stat bonuses?
Not for a report: its Stat Bonuses panel already includes every buff that was active in that fight, pets, gem buffs and exclusive gear skills included. Copy the numbers as they are. For an army you entered without buffs, use the Buffs buttons under the stat bonuses instead of changing the numbers, so you can switch them on and off.
How do buffs add up?
As in the game, every buff on a stat is added into one percentage and then applied to the stat bonus: a 400% attack with +30% in buffs becomes 400 × 1.3 + 30 = 550%. The other side's debuffs (Titan Roc, Snow Leopard, Frostscale Chameleon, and the Attack and Defense down items) are taken off that percentage. Deployment capacity adds troops instead.
Which joiners count in a rally?
Every joiner's troops fight. Of their heroes, only the first hero's skill counts, and only the four highest-level first skills, as in the game.
Why does a fight with no heroes give almost the same result every time?
Most of a battle's luck comes from hero skills. With no heroes the simulator plays nearly the same fight each time, so the range is very narrow. The real game still varies a little.
Is my screenshot uploaded anywhere?
No. Screenshots are read on your own device. Nothing from them is sent unless you choose to share the report with the accuracy data.
How accurate is it?
It picked the winner in 788 of 832 real battle reports, at every stage of the game up to T12 Fire Crystal 10. The accuracy page has the full breakdown, including where it is weakest.
