Movement Speed

Movement Speed dictates how fast a unit moves. Movement speed is calculated in units per second. Movement speed is hard capped at 550, with few exceptions. The minimum movement speed is capped at 100.

Formula[ | ]

Movement Speed = ((Base Movement Speed + Flat Movement Speed Bonus) * Percentage Movement Speed Bonus) * [(Movement Slow * Slow Resistance) per Movement Slow debuff] Rounded

To clarify, here's a theoretical example:

A hero with 305 Base MS with the items:

Marchers (+45 Movement Speed)
Dawnbringer (+10% Movement Speed)

And with the following buffs and debuffs:

Buff 1 (+12% Movement Speed)
Buff 2 (50% Slow Resistance)
Debuff 1 (-25 Movement Speed)
Debuff 2 (40% Movement Slow)
Debuff 3 (30% Movement Slow)

Therefore, this is what the formula would be: ((300 + 50 - 25) * (1 + 0.1 + 0.12)) * (1 - 0.4*(1-0.5)) * (1 - 0.3*(1-0.5)) = (325) (1.22) (0.8) (0.85) = 269.62 -> 270

All percentage-based MS bonuses are calculated together and add based on the flat MS bonuses. Each Movement Slow debuff is calculated separately.
