While wearing this Amulet you gain the following benefits:

• Your Strength Score increases by 2 up to a maximum of 20

• You have advantage on Charisma (Persuasion) checks made to interact with dragons and dragonborn.

If you are not a dragon or dragonborn you gain the following additional benefits while wearing this Amulet

• You can read, speak and write Draconic

• You have resistance to the damage associated with the ancestry.

• You can use your bonus action to exhale destructive energy. You exhale a 15ft cone of energy determined by your draconic type, the save is dexterity. The DC for this saving throw equals 8 + your Constitution modifier + your proficiency bonus. A creature takes 2d6 damage on a failed save, and half as much damage on a successful one. The damage increases to 3d6 at 6th level, 4d6 at 11th level, and 5d6 at 16th level. After you use this feature, you can’t use it again until you complete a short or long rest.

• You determine your ancestry each day by rolling 1d6. Evil aligned creatures become chromatic and good ones become metallic (neutral creatures choose this when they attune)  

1-white/ brass
2-black/copper
3-green/bronze
4-blue or silver 
5-red/gold
6-choose one of the above 

In addition while attuned to this pendant you have a 50% chance each week to gain a draconic physical feature from the following table. Roll 1d6 if you already have the feature reroll. If worn long enough, the wearer will eventually acquire all of these features. The features are purely cosmetic and they fade over the course of 1d4 days when the crown is no longer attuned.
