Item stats

The raw statistics the item grants, as listed in the game data for the current patch, next to its total cost and sell price shown above.

Passive and active effects are not turned into numbers here: two items with the same lines can play very differently once their passives are taken into account.

Build path

The components this item is built from, and the items it can be upgraded into, taken from the game's recipe data for the current patch.

Each icon links to the item page. The gold cost of the finished item is the sum of its components plus a combine cost, which is why buying components first never costs more than saving up.

Patch history

Changes made to this item, patch by patch, most recent first, as published in the official patch notes.

Cost, stat and passive changes all move the win rates above: when a figure jumps between two patches, look here first.
