Movement speed is a Hero statistic that represents the rate at which a hero travels across a map. One movement speed point translates to one game distance unit traveled per second (as a frame of reference, Lt. Belicas' diameter is 450 units). For example, a hero with 1350 movement speed will be able to walk three times the speed of Lt Belica in one second.
Each hero begins the game with a base amount of movement speed, ranging from 450 (e.g. TwinBlast and The Fey) to 472.5 ( Countess and Rampage). For a list of all Heroes' base movement speed, see base Hero statistics.
This base movement speed can be increased by cards and reduced by slows. These effects can come from Cards and Hero abilities.
A Hero's movement speed is given by the following formula:
(Base Movement Speed + Flat Movement Bonuses) - (1 - The Highest Slow Ratio × Slow Resist Ratio)
