Random Targeting Spell

[Uberlord]

I need a spell that hits 3 random targets around with a lightning beam, dealing damage based on stats.
Any ideas how that random targeting of exaclty 3 enemies could be acomplished?
Also i have some minor problems with the beamlike effects (from caster/point to moving targets) for trigger spells, if anyone got time to make my a quick example map or just to explain, that would be great.
Thx

Steps

1 - Pick all units within the area you want the spell to hit
2 - Pick 3 random units in the said group
3 - Inflict damage based on caster stats
4 - Get a dummy caster to hit said 3 with a no damage chain light.

What I seem not to find is the 'Pick 3 random units in the said group' part. :/
How ecaxtly do I do it?

 

[Pharaoh_]

• Set Group1 = (Units in (Playable Map Area))
• Set Group2 = (Random 3 units from Group1)
• Custom script: call DestroyGroup (udg_Group1)
• Custom script: call DestroyGroup (udg_Group2)

Both are unit group variables.

To be more precise where the function came from, it's under "Unit Group -> Pick Every Unit In Unit Group And Do Multiple Actions -> Random N Units From Unit Group"
