Help with a spell

[NhazUl]

Here's the spell I t'm trying to make:
Every second of the spell (it's channeling) all damage taken on the map is collected. The casting unit is damaged for this value, and the AoE around him is damaged for the same value multiplied by a number.
I have made a dummy channeling ability, and the following triggers:
1.Begin Casting - Turn on Trigger 4 and 5
2.Finish Casting - Turn off Trigger 4 and 5
3.Stop Casting - Turn off Trigger 4 and 5
4.

• Event - Unit takes damage (missing, there is a function for a specific unit only)
• Action - Add Real (Damage Taken) to DamageTakenVariable
• Unit - Damage Casting Unit for DamageTakenVariable
• Unit - Damage Area around Casting Unit for DamageTakenVariable*X

5. Every 1.00 seconds of game time - Set DamageTakenVariable to 0


Any ideas how to make it work?

try this

make it

• Event - A unit is attacked
• Action - Add Real (Damage taken by (Attacked Unit)) to DamageTaken

this isnt tht specific i might have wrong trigger (i mean they arent exactly like i typed them but there are things like tht anyway)

But it must also include damage taken by spells and via triggers.
