[Trigger] Storm Bolt ability

[Primstan]

Hey, I require your assistance with a spell. Basically, I want storm bolt to deal area damage with lightning effect, but how do I deal damage upon bolt landing, when it reaches selected target?

I would try a damage system.

When the damage occurs, you could either loop through nearby units (unit group) and cast a spell dummy chain lightning or learn about lightning triggers.
