What attack spells work under water?

[BewareTheBarnacleGoose]

I think basically anything that does NOT say "cannot be cast underwater".

In general, Astral spells work fine underwater, water and earth have options, but air and fire don't really (I think fire only get's one spell- incinerate). And blood obviously dosen't work when your slaves drown (but you can cast blood boil, for what it's worth).
