How can anything conceivably be semi-omni? This is akin to semi-infinite. Jiskran (talk) 23:26, June 26, 2012 (UTC)

Perhaps it blasts within a range of, say, 355 degrees? I'd say that'd be pretty close to blasting in any direction. ProfessorTofty (talk) 06:13, August 15, 2012 (UTC)

Perhaps 180 degrees, as the image suggests? It'd be "half-a-omnidirectional-blast". --  Seth Cooper  owl post! 10:56, August 15, 2012 (UTC)
