Being able to cast waterbreathing makes it so you can have a storm giant save your party after their ship gets sunk in the middle if the ocean by a kraken or dragon turtle.

 Weirdly specific, but I see your point. :D

Wish storm giants could be Playable characters.  

*has 29 strength score* OP
*CR only 13* WHAT?!?!?!?!?!
I expect higher CR if it has a strength score of 29.

This might be a good match for my Dragonborn.

It's like Zues

That sounds pretty poggers bro

I completely agree, their Amphibious, they don't need to cast water breathing.

 Since they're primarily good creatures it's more likely they'd cast it on allies so that they may aid the giant if they need to be underwater.

They can cast it on others in order to take them underwater like Tom hanks was taken in splash

whats your favorite weapon?

The reason they can cast Control Weather three times a day is so that if somebody (a king, for example), made a Storm Giant very particularly angry, aforementioned Storm Giant could go to the place that person lives (say, the capital of their kingdom?) and create a storm that never ends, as they could simply recast Control Weather every eight hours, until the offender made it up to them somehow, which could be as simple as a formal apology, seeing how Storm Giants can be.

Dice Christ, what are these comments...

water breathing is so that a storm giant seer or what have you who keeps to their underwater castle can still entertain surface dwelling guests.

Stat blocks like these are generally the average soldier of a given creature. So this is what your average storm giant who'd be outfitted for war is capable of. A dedicated seer or spellcaster would have a spellcasting trait in addition to their innate spells. It's like how all mind flayers can cast dominate person innately, and then Volo's Guide introduced the stat block for a mind flayer psion, one who had more intensely studied how to use their psionics like spells.

 For non amphibious friends. It says they don't like others of their kind not that they are 100% solitary

Eeeeyyy, it's ya boy Zeus

Storm Giants are absolute chads compared to every other giant, look at that strength score compared to a Hill Giant's

Quote from Bruuze >>

Well, that's kinda like comparing a Herculean half-god to an idiotic glue-sniffer, but I see the logic.

  This cracked me up.

They seemed a little lonely to me, so I gave them lightning wolves as companions in my homebrew.

So wait this has the storm giant belt?
