Cania Upbringing II

Ability Score Increase: Choose one ability score that does not benefit from an Ability Score Increase from a parentage. This score increases by 2.
Icy Weapon: Starting at 3rd level, as a bonus action, you may freeze one melee weapon that you are currently holding. For one minute, melee weapon attacks with the weapon deal an additional 1d6 cold damage. You must maintain concentration during that time, as if you were casting a spell. If you lose concentration or lose your grip on the weapon, it warms quickly, returning to a normal temperature. Once you use this ability, you can’t use it again until you finish a short or long rest.
Languages: You are fluent in any one standard language and any one other language of your choice.
