Challenging spell question

[MintJulep]

Let's say there's a spell that creates caravans that channel lightning between them:

As individual caravans move around in different directions and speeds, the lightning channelling between moves with them as well, changing the overall shape of the formation.

The question is: What's the best method of making the lightning damage any units that walk through it?

 

[Dirac]

Integer A from 1 to Distance between units/10

Set Slide = Slide + Distance Between units/10
Pick every units in Position of unit Offset by Slide towards angle between units and do (Actions)

Dmg unit


Handwritten, hope that useful too

If we had a 5x5 grid of caravans set 400 units apart from each other, that would make a total of 2000 points the trigger handles each run-through. Set to periodically trigger every .2 seconds, that's 10000 points created and handled every second, in addition to the picking every unit action - so I'm worried if lag might be an issue for that particular method.

i would put invisible dummy units with immolation along the lines....

Why not just go along with what Dirac said, and then keep it to players only, who got Blink? Then it's a Survival Map, on another level :b
Then you need to put a big cooldown on Blink, so you can't use it carelessly.
