Winter Walkers are Really Cool, Actually

So let me get this straight. Winter Walkers get PwT for free, as well as Ice Knife, Ice Storm, and Cone of Cold (because they didn't have enough AoE's already).

Additionally, starting at level 7, they get an out-of-combat healing feature that also grants their entire party advantage on frightened saves for an hour...just because.

They *also* get the standard 1d4/1d6 damage bump at level 3, but this time it's cold damage and ignores cold resistances.

And on top of that, at 11th-level, they can frighten *and* immobilize a target that hits them with an attack.

But what I really like is, of all things, how the subclass interacts with Hunter's Mark. It actually bothers to modify the spell in a way that makes it worth casting at higher levels. And honestly, when you take all of it into account, it's kinda crazy. A single-classed, 20th-level Winter Walker will be attacking with permanent advantage for an additional 1d10 per attack, will gain 1d10 THP, prevent the target from disengaging (away from your angry Barbarian friend...or yourself), become incorporeal, gain immunity to cold, *and* passively deal 2d4 cold damage to creatures of their choice within 15 ft at the start of each of their turns for a minimum of one hour. All of that together just for casting a 1st-level spell that doesn't even cost you a spell slot and can't break concentration. Like, yeah. I kinda get why they kept concentration on HM now. If this is what they're vision is for the class moving forward, I can get behind it. It's not perfect (the THP conflicts with Tireless and the cold damage will be easy to negate by higher-level enemies), but I see the vision.

I do wish it had a more direct offensive boost at 11th-level like an additional attack or something. But that capstone dealing 2d4 in an emanation every round for minimum one hour seems pretty busted on paper.
