How to remove/add a spell with its level staying intact?

[Falkonic]

Acutally locking the spell would be sufficent as well. I just don't want a certain spell to be used in a certain area...

You can use Player - Disable Ability but it will disable for all units.
Another option is to store the level into a variable then remove it. When it is added, set its level to the stored variable.

Latent heat give the most applicable solution.
In AOS or Arena maps, it's possible to use disable abilities as only one hero present. But sometimes it's not applicable, which means the second trick is the best way around.
The variable should be different for each caster, if there are multiple levels and multiple heroes uses the spell, as it might return wrong level when restored.

I am in the fortunate position that I only use unique spells / not share them among units. Thanks for the fast Answers.
