Tool Usage
Q: How does the Resource Optimizer work?
The Resource Optimizer uses a sophisticated mathematical algorithm combining bisection method and greedy allocation to find the optimal distribution of your budget across multiple resources. It calculates the cost-effectiveness of each upgrade level and prioritizes purchases that give you the best return on investment. The tool considers diminishing returns, meaning it automatically balances upgrades across different resources rather than maxing out one at a time.
Q: Why are my optimization results different each time?
If you're getting different results, make sure you're entering your current levels accurately. The optimizer calculates costs based on your starting point, so if you've purchased upgrades since your last optimization, you'll need to update those current level values. The algorithm itself is deterministic - same inputs will always produce the same optimal result.
Q: Can I use the Resource Optimizer for partial budgets?
Yes! You don't need to spend all your resources at once. Enter any budget amount you're comfortable spending, and the tool will optimize that specific amount. This is useful when you want to save some currency for future unlocks or are planning a specific purchase strategy.
Q: How do I save my favorite hero layouts?
On the Hero Layouts page, click the star icon (☆) in the top-right corner of any layout card to save it as a favorite. Your favorites are stored locally in your browser, so you can quickly filter to see only your saved layouts using the 'Favorites' button. This is perfect for bookmarking the layouts you use most frequently.
Strategy & Progression
Q: What should I prioritize early game (Rank 1-50)?
In early game, focus on XP teams first as they provide the fastest progression multiplier. An updated early game progression guide is in the works, and we will link it here once published.
Q: When should I switch from XP farming to pushing layouts?
Switch to pushing layouts when you're stuck on a wave and can't progress with your XP team. Push until you unlock the next major milestone (like a new resource tier or hero), then switch back to XP to level up efficiently. The key is alternating between XP phases and pushing phases rather than pushing constantly.
Q: How important are hero layouts vs individual hero strength?
Both matter, but synergy often beats raw power. A well-optimized layout with average heroes will typically outperform a random team with maxed heroes. Certain hero combinations unlock multiplicative bonuses through their abilities, which is why you'll see the same heroes appearing together frequently in optimal layouts.
Technical & Account
Q: Do these tools collect my game data or personal information?
No. All calculations run entirely in your browser using JavaScript. We don't have a backend server and we don't require any login. Your favorite layouts and preferences are stored only in your browser's local storage and never leave your device.
Q: Can I use these tools on mobile devices?
Yes! The site is fully responsive and works on phones and tablets. However, for the best experience with the Resource Optimizer's detailed inputs, we recommend using a tablet or desktop for your initial setup, then referencing results on mobile during gameplay.
Q: Are the hero layouts updated for the latest game version?
We strive to keep layouts current with major game updates. Hero layouts are based on proven strategies from top players and are updated when significant balance changes occur. If you notice an outdated layout or have a better strategy to share, please contact us.
Q: What browsers are supported?
These tools work on all modern browsers including Chrome, Firefox, Safari, and Edge. We recommend keeping your browser updated to the latest version for the best performance. Internet Explorer is not supported.
Game Mechanics
Q: What does 'Ultra XP chance' mean in some layout descriptions?
Ultra XP chance is an upgrade you unlock through progression that gives you a percentage chance for enemies to drop significantly more experience than they otherwise would. Once this chance reaches around 7%, certain hero combinations become more efficient because they can reliably generate ultra XP. Check layout descriptions carefully for these threshold notes.
Q: How do I know which resource tier to prioritize?
Higher resource tiers (Level IV, V, VI) provide larger percentage bonuses but cost exponentially more per level. Use the Resource Optimizer to see the actual cost-effectiveness.
Q: What's the best way to farm gold efficiently?
Use dedicated gold farming layouts (available on the Hero Layouts page filtered by 'Gold Farming' category). These layouts include heroes with gold boosting abilities & synergies. Combine gold farming layouts with appropriate gold% upgrades for maximum efficiency.
