Build Lab

Find the items and talents that answer the enemy, or put any build together and see what it is strong and weak against.

Your hero

Enemy team

Everything is optional: add enemy heroes, the items they have built, or both. Without items, a hero is read from its usual ranked build.

  1. Enemy 1
  2. Enemy 2
  3. Enemy 3
  4. Enemy 4
  5. Enemy 5

Add an enemy hero or item to see what to build against them.

How it works

Each item's stats and passive are read into what it threatens with and what it answers. The enemy's threats come from the items you enter, or from each hero's usual ranked build. Suggestions follow your hero's damage type and favour items its ranked builds win with.
