Making zombie move faster than their maximum (capped) speed

[Robeloto]

I want to make a certain zombie I made move even faster. The speed for zombies is capped at a certain point. Maybe apply the zombie a buff to move faster on certain terrains? I know you could add movement factor on blocks, but that applies for both the player and the zeds. I only want to make it for one certain zombie. And I am not sure how to do it. Any help appreciated!

Edit: If that is not possible, maybe you could make the zombie give the player a buff when he is near the player so player runs slower than the zombie.

Nvm, I just remember how to do it without any buffs. Just adding this under the effect groups in the entityclass. With the value of 2, the zombie will be ultrafast

<passive_effect name="WalkSpeed" operation="base_set" value="2"/>

<passive_effect name="RunSpeed" operation="base_set" value="2"/>
