[Spell] Mana Steal - How to do?

[FreudTastic]

Hey everyone! I am working on a Blood Elf project right now, that may or may not be released into an open, late Beta soon... but I need help with a spell/ability that I do not really know how to make.

Think of it this way; You want a unit be able to steal mana upon auto-attacking an enemy unit, or creep. Sort of like how life steal works, except... well, mana! How do I do this?

You need a damage engine (Preferably Bribe's system: Link). Then whenever that unit attacks, add mana to it through trigger.

EDIT: Example trigger

Mana Steal Events Game - DamageEvent becomes Equal to 1.00 Conditions (Unit-type of DamageEventSource) Equal to Blood Mage Actions Unit - Set mana of DamageEventSource to ((Mana of DamageEventSource) + 50.00)

Nice, thanks! But, how do I do it if I want it to be a researchable ability, as well? Your Trigger example might be the solution for my problems, but I'd like the ability to be available through research.

Just add a condition

• (Current research level of YourUpgrade for (Owner of DamageEventSource)) Greater than or equal to 1

P.S Didn't tested yet.

@UndeadImmortal
It steals mana also with spells and code damage.

Try first checking if damage is physical,via Detection Of Physical Damage system
