[@Teyao] Miraculously, your character is pretty good, and there's not an awful lot to say, but let's see here...

First is the culture of the Jotun, which for the most part is about right. They live in seclusion in order to practice their peaceful ways, despite their immense strength and physical superiority to humans, they are in the end a dwindling race. However, they are also pretty wary of the ways of the world outside, so some level of skepticism would be just right for your character.

Anyway yeah that's pretty much it, those skills and everything for combat make sense and don't sound overly powerful, in fact I actually think you need another technique that doesn't rely on having a Cryo user around. Ice Armor is cool and all, but you essentially cannot use it without a Cryo friend or an icy environment. You can note it gives him the uncanny ability to not be frozen in place by Cryo though, so he becomes immune to a status effect.

Otherwise I'd give him another something, or make Water Barrage have less drawbacks and be your bread and butter for offense. Really, up to you. Maybe something using his axe and shield too.

Anyhow seems good otherwise.
