Build simulator

Put a build together — hero, level, six items, emblem, talents and spell — and read its computed stats, source by source. The page link keeps the build: copy it to share.

The spell changes no permanent stat: it is kept with the build for sharing.

How the stats are computed

Hero base stats come from the wiki, which only publishes them at levels 1 and 15: in between they are interpolated in a straight line, which remains an approximation. HP regen is only given at level 1, and base attack speed is not listed at all: only the percentage bonus is shown.

Item attributes are read from their wiki pages, emblem and talent figures from its “Emblems” page. A unique attribute only counts once per item, a passive with the same name on two items only works once, and two pairs of boots do not stack: the simulator flags it. Conditional passives (below an HP threshold, after a skill…) are listed but not counted.

Caps applied: 40% cooldown reduction, 45% with Enchanted Talisman's Magic Mastery passive, and 100% crit chance. Crit damage starts at 200%. The game caps attack speed at 3 attacks per second, which cannot be applied without a base speed.

Effective HP divides HP by the game's damage multiplier, 120 / (120 + defense). The damage reference applies the same formula to a target's defense after penetration: defense × (1 − % penetration) − flat penetration, never below −60.

Measured builds come from the game's academy, relayed by arena.rone.dev: for each hero, lane and rank, the three core items of the most played builds, with their win rate and share of games. The simulator shows those sharing at least two items with yours.
