Picking only 10 units within range of a Certain Unit

[IDF_ALLAH]

Caster uses a spell and then picks 10 friendly units within 600 range and kills them, but only if there are 10 or more units in range and only 10 would die.

What would I use for this?

Basically you have to trigger the ability... You should try to use a loop for "integer A from 1 to 10" and so make the picking of 10 units that will be affected. I can't make an trigger text at the moment but maybe i will when i have time.

Thats wrong, do this, pick all units around him, if its less than 10 do nothing, else pick 10 random units from the group, and kill them.
