Winter’s Claw

You were raised in blood and blizzard—among raiders, beast-hunters, and warriors who believe only strength can bring peace. You do not shy from pain; you revel in it.

Ability Score Increase. Strength +1

Relentless Advance. When you take the Dash action, difficult terrain made of snow or ice does not cost you extra movement. During this movement, you may move through hostile creatures' spaces as if they were difficult terrain, provided they are no more than one size larger than you.

Savage Ferocity. Once per turn, when you hit a creature below its hit point maximum with a melee weapon attack, you may deal extra damage equal to your proficiency bonus.

Hunter’s Resilience. When you are reduced to 0 hit points but not killed outright, you may instead drop to 1 HP. Once you use this feature, you must finish a long rest to use it again.
