Request: Optic Flare

Request: Optic Flare

I would like to have an ability that is similar to the medic's optic flare ability in Starcraft. I do not know how to adjust the vision of units through spells.

how does it work???

Blindes target unit so you can se only really short range.
Im not sure how to make it...perhaps use some ability that affects vision (item - goblin noctovisor)

or try to experiment with the upgrade that gives seeing range.

I would suggest setting the editor to accept negative values (in file--> prefences), and using some ability that increases sight range, not just gives you ultravision.
if that cannot be done, try using a visiblity modifer, radiating from dummy units sorrunding the caster (problem: stops other units...)
