Cold Front (5e Feat)
From D&D Wiki
Prerequisites: Constitution 13 or higher, and must be an ice fairy, variant
Like the ice you are born from, you have begun to harden your body to make yourself harder to break. You gain the following benefits:
- Your Constitution score increases by 1, to a maximum of 20.
- You have immunity to cold damage instead of just resistance.
- When a creature within 5 feet of you hits you with a melee attack, you may use your reaction to reduce that creature's movement speed by 10 feet until the end of that creature's next turn. You may use this feature a number of times equal to your proficiency bonus, after which you must finish a long rest before you can use it again.
