[Solved] Damane Depends on yo' current mana

[Venkolm]

Alright guys, for someone like me, asking something like this, lool damn shame, but really, i was busy with some RL stuff, and suddenly i realized... i can't make this spell, because i forgot how!
So the spell i am trying to remember how to make, is:
targets one unit, it's not AoE, you can say it's some kind of a bolt, yea, but how to make it to deal damage, depending on the Hero's CURRENT mana.
Triggers, but still, which ones?

 

[Kaijyuu]

• Unit - Cause (Triggering unit) to damage (Target unit of ability being cast), dealing (Mana of (Triggering unit)) damage of attack type Spells and damage type Normal

I don't know if this will use the mana of the unit before or after the mana cost of the ability is deducted, though.

 

[Venkolm]

This is why, there is no mana cost.
Yea, i woke up and remembered

 

[UreDe4D]

so just use Kaijyuus Trigger for the Damage and set the Mana of the caster to zero afterwards, the mana cost won't show in the tooltip, but i guess you can put some text saying "variable" or "depletes all you mana"
