You can use your action to exhale destructive energy. Your silver draconic ancestry allows you breath a cold breath in a 15 ft. cone. Each creature in the area of the exhalation must make a Constitution saving throw. The DC for this saving throw equals 8 + your Constitution modifier + your proficiency bonus. A creature takes 2d6 Cold damage on a failed save, and half as much damage on a successful one.
At Higher Levels: The Cold damage increases to 3d6 at 6th level, 4d6 at 11th level, and 5d6 at 16th level.
After you use your breath weapon, you can't use it again until you complete a short or long rest.
On your turn, you can enter a rage as a bonus action.
While raging, you gain the following benefits if you aren't wearing heavy armor:
• You have advantage on Strength checks and Strength saving throws.
• When you make a melee weapon attack using Strength, someone else's voice, a lion's roar, a beating of drums, or any other sound you choose. The sound continues unabated throughout the duration, or you can make discrete sounds at different times before the spell ends.
If you create an image of an object - such as a chair, muddy footprints, or a small chest - it must be no larger than a 5-foot cube. The image can't create sound, light, smell, or any other sensory effect. Physical interaction with the image reveals it to be an illusion, because things can pass through it.
If a creature uses its action to examine the sound or image, the creature can determine that it is an illusion with a successful Intelligence (Investigation) check against your spell save DC. If a creature discerns the illusion for what it is, the illusion becomes faint to the creature.
