Stacking / Detecting stacked poison

[s3rius]

Hi there,
I was wondering if there is a way to stack poison through a trigger, and how it's possible to detect how often it is stacked?

Also, is there a way to add a specific buff? I looked into the function and managed to find out that it actually uses RemoveAbility() to get rid of the buff, but it seems not to work with AddAbility
Thanks to any helpers.

You add a buff by making a dummy unit, and casting an ability that gives a buff, (For example Bloodlust) on the unit you want to have a buff.

There is already a poison that stacks, but if you want to make things stack through a trigger, you'll have to make multiple copies of the same ability, with different buffs, and then cast them on the unit. If you cast the exact same ability, it will just overwrite the current one, and reset it's duration.

Sorry, I think I was a bit unclear.
I know that there is a stacking poison, but this, of course, only stacks when the unit is hit several times (and it think from different enemies).
When I have, let's say, this poison already 3 times stacked on my hero I would like to use a trigger to increase it to 4x stack.

If that's not possible I'll use a dummy unit

Make a dummy unit without an attack animation, but with an attack, and a attack cooldown of something like 20.0 seconds (So it can only attack once)

Give it that ability.

Order it to attack that unit, then remove it.
