Erm... Isnt that a simple blink ability?... There was a map somewhere with similar ability while the caster is visible though... Will try to give you the link.
Edit:
Here you go. I think its this one. Download the file named Swarm_mine as I recal. The first one. http://www.sc2mapster.com/maps/lightning-stream/
Try it out, the Tassadar in that map has similar ability called "Dash". And let us know if thats what you was trying to achieve.
Demtrod Regular ShmoeIt is possible to make the Launch missile effect launch the caster, and move it from the launch location to the target location?
If not, I want to make the missile look like the caster and make it teleport the caster to the target location upon impact. In that case, how can I make the caster invisible (to all including the owner) while the missile is moving?
