Which undersea summons are worthwhile?

Underwater Combat 101:

1) You must have Shark Attack. Beeline toward it. It is your early Atom Bomb.

2) Summon Asp Turtle. Oh my... yes, summon some Asp Turtles. They are extremely nasty.

3) Summon Water Queens. They regenerate all hit points each turn. Equip them well.

I would avoid fighting an undersea battle without both shark attack and friendly currents cast. You can get a trident from construction 4, I think, that casts currents each battle for free. You'll have to cast shark attack, but it's well worth it.

I only really use sea trolls and battle summoned water elementals (living water) when fighting underwater. I always try using shark attack and friendly currents with them.

If you can get the 3 water queens then they should be your priority for your water gems.

Items like boots of quickness, jade armour, bottles of living water, water braclet and robe of the sea are good items to forge with water gems.

Finally, the global Maelstrom is perhaps the best gem producing global in the game, as it produces the most gems, 27 gems per turn in total. The drawback is 15 of them are water gems and its Evo 8.

Leviathans worth their price if you have death/water.
