How to do AOE and DPS trigger which scale attribute?

[HolyWillRise]

For example:
Slam/Thunder slam for AOE, i did it but i damage myself too. (Scale with STR)
DPS skill - Starfall which scale with X INT damage
For example 5xINT (INT 100x5 = 500 damage total) for the full duration

Instant aoe spells are easy to code for the most part.
However about the starfall, you might have to code the entire spell and set its damage.
I am assuming you are using damage area, yeah it damages everything in that area.
What you should be using is unit groups and damage target.
Here is the tutorial : Single Target Spell for Multiple Units

You cannot change the AoE of an ability outside of the editor and there is no way to make a basic wc3 ability use attributes in any data field whatsoever. As Aeryn suggested your only option to do something like this is to code the spell yourself from the ground up.

You need to make the spell via triggers.

If you can't or don't want to code it, you could use a damage detection system and replace the damage of the skill. Something like: if someone takes magic damage, and the current order of the damaging unit is "Starfall", then set the damage amount to (int x whatever). Little workarounds like this can keep you from having to spend hours duplicating a somewhat complex spell like statfall which is for sure going to require vjass experience and TimerUtils to do effectively.

Or, if you want to be more original, code your own spell with a similar function to starfall, but make it different, so it doesn't look like you're just using wc3 defaults. For example, The Black Road has a spell called "Freezing Field" which creates a bunch of frost explosions around it which deal damage in an area. It's not starfall, but it has a similar purpose.
