[Trigger] Attacks use mana

[asdfblah]

How would I make a trigger to subtract mana from units for each attack? I couldn't find an event for 'a unit attacks'

You don't need triggers for this, you can use a modified feedback spell, or if you want to:

• Mana attack
  • Events
    • Unit - A unit Is attacked
  • Conditions
    • (Owner of (Attacked unit)) Equal to Bad guy
    • (Unit-type of (Attacking unit)) Equal to Mana Attacker
  • Actions
    • Unit - Set mana of (Attacked unit) to ((Mana of (Attacked unit)) - 20.00)
