    Frequently Asked Questions

    How accurate is the damage calculator?

    The calculator uses official champion base stats and item stats from the latest patch. It accounts for armor, magic resist, and penetration. However, some champion-specific interactions may not be included.

    Does it account for runes?

    Yes, you can select rune pages and the calculator will include rune bonuses in the damage calculation.

    Can I compare builds side by side?

    Currently you can switch items quickly to compare, but a dedicated side-by-side comparison feature is planned for a future update.

    Why does my in-game damage differ from the calculator?

    In-game damage can vary due to ability-specific interactions, buffs/debuffs, and champion passive effects that may not be fully modeled in the calculator.
