It sounds like something you'd get out of a D&D campaign, for one thing, and that is exactly what Exalted shouldn't have. Exalted has always been The Not!D&D game, and having a spell whose name is Death Ray is just ridiculous towards that end. It sounds so... puny and insignificant.
Avoiding things that sound like something you'd get out of a D&D campaign is a useless and counter-productive design standard. It's so vague, all-encompassing, and
arrogant. Especially with things like
names. Want to hear some canonical weapons from 3.5e D&D?
