Collision Radius

Jump to: navigation, search

Every Hero in Heroes of the Storm has a Collision Radius (also called Hitbox) which determines how much physical space their character model occupies. The Collision Radius is visible as a green (your own), blue (your allies) or red (enemies) circle beneath the model.

Collision Radius is used to check collision with other frindly and enemy Heroes, Structures and Terrain since those entities can not simultaneously occupy the same physical space. Heroes are however unaffected of the Collision Radius of minions, summons, mercanaries and monsters.

A target is hit by a skillshot or an AoE if the ability hits the circle beneath the model (even the edges count). Larger Heroes with a bigger Collision Radius can effectively use their bodies to block the movement of other heroes. High-level players will utilize these "body blocks" to disrupt the paths of enemies and gain a positional advantage. You can slow people down, prevent them from running behind a gate, or even pin them in an area for your team to kill them.
