Hey -

You could add a branch check to see if a bool variable (isCooldown) is true before casting the spell. If it is true the the spell won’t cast, if it is not true then you can cast the spell. After casting the spell set the variable to true. Then on Tick you can test if isCooldown is true and if so, set a delay for how long you want the cooldown to be, then set it to false.

You can use timers:
https://docs.unrealengine.com/latest/INT/Gameplay/HowTo/UseTimers/Blueprints/index.html

In simple algorithm it will be:

Add two variables into blueprint/code (isCasted - bool and Cooldown - int) and then

Cast event (button/AI/etc)
Branch node (or if) where you check your isCasted variable
If spell not casted (isCasted = false) then you do usual casting actions and set isCasted to true, then start Timer on Cooldown time
In Timer ‘loop’ just reset isCasted variable to true value on complete.
And then if you try to cast spell when isCasted = true, you go to another branch of Branch node where you can add info message (or do nothing)
