There have been a few attempts by others at these (and I am going to link some below for me to check on whilst working on these), but I still feel these Domains have not been captured properly. I really like elemental stuff and obviously it is very important to Kage. I feel too many attempts miss the heart of the element. 3E's alignment of elements with energy types did not help at all, as people are still doing this. It even continued in Pathfinder. For eg Earth domain clerics getting acid powers!
And in some cases Air elemental priests sound like storm priests, then water priests commanding cold powers etc. I see these are very different things.
So, I am going to put together some elemental-based Domains for our clerics. For now, I just want to collect a few other attempts together.
If you have time/could be bothered, have a look at some of these, and see what you like. (I have commented on several, esp in regard to removing the alignment of energy types with elements)
