Disable all unit's ability

[Flux]

Is there a way to disable all unit's ability? The obvious solution is to silence the unit but I don't want a Buff to appear. Setting the mana to zero is not acceptable (don't ask me why). Any other workaround?

Hn, isn't it possible to remove the buff icon ?
I recall not adding something as buff also does not display any.

Use Doom Buff and set that Icon to Black32x32.blp ...

You can create a dummy unit that is part of the requirement for the spell and then treat it as a switch. Remove it to disable abilities and create a new one to enable them again. But this will effect all units with those abilities.

putting a black or transparent 32x32 buff status icon is a problem because when the unit has a lot of buff, you will see a spacing/gap.

Removing and adding abilities work but is a bit overkill.
