Charm ability Help

Looking at the charm ability, I can't find a way to change how many units are charmed. Also the default area is set to 0. Basically I'm adding a second level to the spell and want to increase the units and area. I can't see a way to do this so far without triggering it, so I thought I would see if anyone knows how the ability defaults work.

Sorry if I chose the wrong section to post in.

I'm not sure this will help, but anyway...

- to make AoE charm i guess you have no choise but to use dummy caster or vex's caster system (get it, it makes job hell easier)
- to limit the number of controlling creep, they only way i can think off is setting a custum value everytime you charmed a unit

(set (Target unit of ability being cast) = custum value + 1)
(set custum value = custum value +1)

, then make sure the number of unit charmed is less than the limit charmed unit, if this returns to false, destroy the unit with the lower custum value unitl it reach the limited number of charmed unit.

Indeed, the base Charm ability can't be altered to target an area or affect more than one unit. It must be triggered. I'll move ya to the trigger forum.

OK, I can trigger it no problem. Just wanted to see if I was missing something in the ability settings.
