Maybe I didn't describe it well, but what I meant to describe is closer to (but still very different from) orb of destruction than it is to searing ray. To clarify: You don't have to stand there hitting . as the wave expands, it isn't a "continuously casting" spell like ray. Once you cast the wave, it expands on its own. You can move or do whatever you want after casting—including casting another wave, even another wave in the same direction. It is like a "slow moving" bolt, but in a wave shape. How far the wave extends before dissipating can be set, or spell power dependent.
EDIT: Hell, maybe a spell that lets you set a "bomb" in any direction immediately adjacent to you could be interesting; upon "recasting" the spell the bomb explodes to a very large radius over two turns. (1/2 max radius on turn it explodes, full radius on next turn or something like that.) The flavor here would be that the foo you set releases a powerful wave of (whatever) upon your command, upon your leaving the foo's LOS, or after X turns—whichever happens
first. Only one of these "bombs" can be set at a time. Unlike fulminant prism this glyph/rune/bomb/whatever doesn't count as an ally that takes up a square, but functions kind of like a trap or a cloud—you can walk over/through it, as can enemies. This would also differ from fulminant prism in that there is no smite targeting, you have to put it in some tile adjacent to you, it has a larger radius but doesn't deal damage to full radius until turn following detonation, and you (generally) detonate it upon your command. (Active detonation is intended use, the LOS and turn-based thing is to avoid kiting or scummy behavior with it.)
