What is the eraser trick mentioned in this StarCraft video?

  • Could add "Brood War" in the title. Even though you might not be playing the expansion (which you really should), it'll help differentiate. It's how TeamLiquid does it.

  • Hopefully people realize as they're answering the question that the Eraser Trick doesn't exist in SC2

  • @Atav32 That wouldn't work as Brood War is an expansion, and not everyone plays Brood War when they play the original StarCraft.

1 Answer 1


Here's a summary of what it does:

"Doing the Eraser trick is very easy, you only need two or more Science Vessels with Irradiate researched. To do the trick, simply have your two Science Vessels irradiate each other, and fly them over or near the units you wish to kill. Since Science Vessels are not biological units, Irradiate has no effect on them; however, Irradiate's splash damage hurts surrounding biological units."

  • It's worth noting that Science Vessels have a fairly wide radius (which affects the area of damage) as well as decent speed, so they are perhaps the ideal air unit to irradiate.

  • @JoeyAdams I think it's more about convenience in the SK Terran build order. If you're massing science vessles, it's hard to have the gas and Starport time to build other air units.

    @JoeyAdams "Irradiate is an offensive spell cast by the Terran Science Vessel and surrounds the targeted unit with an aura of radioactive energy. It can be cast on any unit (unless in Stasis) and deals an equal amount of damage (250) over a period of 37 in-game seconds to all biological units within a 2 hex radius of the affected unit. " (from Liquipedia). SV's sight radius doesn't impact the damage dealt by an Irradiate spell cast on it. Feb 12, 2014 at 16:25
