What are the most common elements that Kuros use? And are there some elements they cannot use or are considered rare?

OOC : Kuros are usually stereotyped as being Shadow dragons, buuuut almost all elements are actually common. In the military most factions are determined by element depending on the battle, or each group will have one elemental of each. There aren’t really rare elements, some elements are more common depending on villages, but in the Kurosia the city, it’s fairly balanced. Like Athrenna’s village she was born in was mostly made up of water elemental due to it being a small fishing village. There are also different biomes within the entirity of the Kurosian Mountains where the dragons not living in Kurosia tend to stick to their own elements.

The one element Kuros CANNOT USE however, is Light. The most effective element against them is Light (SO YEE the Light Elemental Skylanders are like fire types to grass types in pokemon x,D). They are physically unable to harness light powers without harming themselves. It’s almost painful for them to even be in the presence of a Light Elemental, just as it irks Light Elementals when they’re near Darkness (at least that’s how I picture it). 

Of course, there are work arounds, like hybrids or some story element to make it possible! I actually do have one character in development that is of Kurosian bloodline yet he’ll wield Light powers. BUUUT long time before he shows up (next generation WHOO). Though even for him, he’s not full blown Kuros so he’s able to wield it as an element.
