Cold Front (5e Feat)
From D&D Wiki
Prerequisites: Constitution 13 or higher, and must be a Fairy, 2nd Variant (ice)
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.
