Savagery of the White Dragon

You possess the unyielding ferocity and freezing magic of the white chromatic dragons, granting you the following benefits.

• Increase your Strength score by 1, to a maximum of 20.
• You can make a single weapon attack as a bonus action. If you do so using this feature, you do not add your ability modifier to the damage. In addition, you can choose for that attack to deal cold damage instead of the weapon’s normal damage type. You can use this feature a number of times equal to your proficiency bonus, and regain all expended uses upon finishing a long rest.
