Ice Tower - Light

Could either be used to freeze creeps and slow bosses, or Could be a Tower that makes them brittle and take more damage when in range of it. Would expand on the options we'd have with Light towers, as I feel they are currently limited to Phoenix, guard spam, and training holograms. I dnt feel that much else is really used in Light.

I like the idea of making this an iceberg for darkness water tower. Or keep it as a light tower and make the iceberg Light-like. Maybe it's not an iceberg, exactly, but instead a solidified mass of holy water or angel tears? Anyway, just looking for a way to make this tower float on water to fit with the theme for next season.
