Chain Lightning (Effect) That follows a unit from a point for 3 minutes

[soulcalibur9]

If anyone has done the Razorgore the Untamed fight from Blackwing Lair. I'm making a replica of that fight. I need to create a Chain Lightning or other spell effect siphon mana or drain mana, to follow a unit for an extended time without doing any damage or effects to the unit. The thing is I'm starting the event with, A Unit Enters a Region. And I want either the entering unit to cast the spell or the effect to follow Razorgore, or the effect to follow him from a point. The only problem with that is the unit is switching teams to Neutral so for some reason he won't cast the spell. If someone could create a trigger that would allow A unit entering a region to switch teams to neutral passive and cast a chain lightning effects that follows razorgore for 2 minutes without damaging him that would be divine.

Thanks so much for even reading this
