Is the Ability Interrupt of Crushing Shock and Venom Arrow on a 4 second Cooldown?

Avran_Sylt

As in, were I to use Crushing Shock or Venom Arrow on a player repeatedly, would I be able to interrupt their ability casts with no cooldown, or would it be a similar cooldown as with stuns?

Interrupt has no cooldown.

Stunning also has no cool down but grants a generic 7 second CC immunity after the stun is broken. CC immunity can be obtained from different sources like skills or potions as well.
