Mmmm, I like the Crystal Golem. Maybe with a little work, could come up with a less generic identity for it, too.
The Adom is sort of like the Living Hurricane, but has some cool lore behind it, you should check it out on the webs!
For the Whirlpool, I wanted to completely avoid "aquatic only" summons. There are a number of useful ones that already get mostly avoided, since they are so hard for land nations to gain solid access to, and if you are aquatic you generally don't want to burn gems on stuff that can't crawl onto land when you're ready - at least, not after the early-mid game.
Ifrit seems popular, he was already in my little black book, and is definitely going into the mix in one form or another.
Also, a powerful shapeshifter could be a TON of fun. Give it multiple shapes with no intention of shifting in combat, but just a bit of uncertainty for the enemy as to which form he will attack in. Problem there is that something like that could be fairly challenging for me - this mod has a significant amount of content, but I am trying to work it out so as to minimize the effort required to achieve desired results.
