Arena Simulator

Build your battle lineup and see how your team stacks up against arena opponents. Rather than spending a real attempt, the Arena Battle Simulator will run each matchup many times with fresh random seeds and report a win rate — the share of those battles your lineup wins — so you can plan your attacks with confidence. This is a simulation, not a prediction — simulation results are not guaranteed accurate and may differ from your actual results in the game. The simulator is built from the same battle engine that powers the game, but it is not a perfect replica of the game and may not account for all factors that affect battle outcomes.

Deploy skills are not used during arena battles and do not affect the simulated win rate — they only factor into the on-screen power shown on the in-game arena screen. Entering them lets you double-check that your hero data is correct by matching that it to your in-game power shown on the arena screen. If your power in the simulator does not match your in-game power, check that you have entered all your hero data correctly. Power data may not update immediately in game if you made recent changes to hero levels or gear, so if you just made changes, the best way to update it is to log out of the game and back in.

All hero information (your roster) you enter is saved in your browser's local storage, so you can come back later and pick up where you left off. Even heroes that are not in your lineup are persisted and kept "on your bench" so you can easily swap them in and out and their levels, stars, gear, etc will be restored from your last entry. This also allows you to easily swap heroes in and out of your lineup or swap hero positions without having to re-enter their data each time. Your roster — your heroes and their levels, stars, and gear — is saved in your browser and shared with the Patrol Simulator, so a hero you set up in either tool is recognised in the other. Your arena lineup is saved separately, so patrol and arena can field different teams.

The most accurate simulations will result from having full enemy hero data, which includes: gear strength, exclusive equipment levels, star pieces, and skill levels. However, realistically, that is not always available (especially in cross-server arenas). When it is not, you can use one of the five presets quickly set an approximate level for all of that information:

• Whale (Legendary gear, everything maxed)
• Well Geared (Legendary gear, ≈75% stats)
• Above Average (Legendary gear, ≈ 60% stats)
• Average (Epic gear, ≈50% stats)
• Undergeared (Rare gear, ≈25% stats)

If the enemy lineup you are simulating is currently in the top 100 of the arena, you can get all this information from tapping on their profile in the arena and then tapping on the magnifying glass icon next to Defense Formation. This will show you all of the information necessary to enter into the simulator with the exception of the Deploy Skills, which are only used for the Power Display number in game but don't actually contribute to Arena Battles. If they are not in the top 100, you will have to estimate their stats. In the future, we plan to add a "screenshot upload" feature that will allow you to upload a screenshot of the Defense Formation screen and have the simulator automatically extract all the necessary information from it.

The simulator currently only supports a roster for one game account. If you have multiple accounts, you will have to re-enter your heroes for each account. We are working on a multi-account feature, but it is not yet available.
