[@Enkryption]Main Weapon and Secondary Weapon types have to be more specific. If melee, what class of melee weapon, and if ranged, what class of ranged weapon. Just to give an idea of some of the ranged weapon classes, here's a few; handguns, long rifles, bows, crossbows, heavy ordinance.

Since you've got a rail-shotgun that fires beanbags, you might as well be using a sniper rifle. So that'd be a long rifle.

Your fighting style should also be defined. I would like to note it doesn't have to encompass all your weapons, but if you can do it then go ahead. All you have there are the boons but not what the fighting style actually is.

Next is techniques. Shock and Awe is fine. Kirin's Eyes though, I wouldn't say are too powerful, because I can just slap a limit on it but it's just that clairvoyance is a whole other thing. Such precise clairvoyance even if it's just a dozen seconds into the future is pretty much in a different realm of power that she shouldn't have, even if it's via a curse from birth.

My suggestion if you want to keep an eye power, is that it's not her default state as described, but must be activated. The effect can be something like hyper-perception, where she can perceive incredible speeds, or... Something else if you have other ideas.

Ionizing Purity in a more practical sense would allow you to resist poison, you're free to add that if you like.

Anyhow, I do like a lot of the things here like the coven and such, it's actually not too far from what I'd consider a well-established coven seeped in tradition. My only note is that visions are rare, and masterless ones even rarer, as it's typical that a vision would disappear with the death of their user. And even if you found a masterless one, there's an incredibly slim chance it would resonate with a new user. So I actually suggest she had simply been granted one naturally via a pivotal point in her life.
