Defend - Won't cost mana?

[TheDanish]

Hello all.

I've been having an issue with Defend. I merely want to make the Defend ability cost mana. The units that have this ability do have a mana pool, but even when I change the line "Stats - Mana Cost" to a certain amount, when I run the map the tooltip does not indicate that it costs mana, and when the unit uses Defend, it doesn't use mana.

Is this a known issue?

Trigger it.
Event: Units begins casting an ability
If: ability = defend
Do: set mana of triggering unit = mana of triggering unit - <value>

While that'll get the result I want, it doesn't look good. I want the tooltip to indicate the mana cost. It should just be a matter of changing the mana cost of Defend from 0 to 20 or 50 or something, but that doesn't seem to work.

Damn, then you need to do 2 spells. One for activating, one for deactiving. While using the activating spell, add the defend ability and order the unit to trigger it. Immadietly after the order just disable the ability, and add the deactivate spell. While casting that spell, just remove the defend ability.
