[Spell] trigger: Mana Loss on taking damage

[jintlox]

If a unit takes damage, deplete attacked unit of the same amount of mana
Already got the damage part done, just need to know how to get the exact amount of health damaged.

So, like this?

• Actions
  • Set VariableSet Real_Mana_Depleted = (Damage taken)

Like that

• aeiou
  • Events
    • Unit - A unit Is attacked
  • Conditions
    • Or - Any (Conditions) are true
      • Conditions
        • (Unit-type of (Attacked unit)) Equal to Daemon
  • Actions
    • Set Real_Mana_Depleted = (Damage taken)
    • Unit - Set mana of (Attacked unit) to ((Unit: (Attacked unit)'s Real Field: Mana ('umpc')) - Real_Mana_Depleted)

Now that I've tested it, the event doesn't seem to be actually triggering.

It's because you're using the "A unit is attacked" event, you need to be using the "A unit takes damage" event. You can't add it as a generic unit event, you need to add it as a specific unit event. The way I usually get around it is that I make a second trigger that goes like this:

• Add Unit to Group
  • Events
    • Unit - A unit Is attacked
  • Conditions
    • ((Triggering unit) is in UnitGroup_DamageEvent.) Equal to False
  • Actions
    • Unit Group - Add (Triggering unit) to UnitGroup_DamageEvent
    • Trigger - Add to Your ManaDamage Trigger <gen> the event (Unit - (Triggering unit) Takes damage)

The action you're looking for is called "Trigger - Add New Event"

If a unit takes damage, deplete attacked unit of the same amount of mana

Mana shield/Mana Burn? Sounds a lot like an object editor ability.

You can use the Arcane Tower's feedback ability. It burns fixed amount of mana of target every hit.
