You have a +2 bonus to attack and damage rolls made with this magic weapon.

While attuned to wyvernspine you can read and write draconic, and you have advantage on Charisma checks while interracting with dragons. You also have advantage on Intelligence checks regarding information on dragons. You also gain advantage on saving throws against the breath weapon attacks of dragons and against being frightened by a dragon.

The bow has four charges, which all return each day at midnight. You may use these charges by speaking draconic, and doing so activates the following traits:

Tyrants Agony: After you hit an attack, you whisper a word in draconic that evokes sharp pain in its new wound. Expend 1 charge and it must make a DC 17 Constitution saving throw or fall prone from the pain. If the target is a dragon it has disadvantage on its save.

Twinned Arrow: When you make a ranged attack roll you may expend 2 charges to have the bow duplicate the fired arrow, making a seperate attack roll for the new arrow. You may only do this once per non=duplicated arrow you fire. If the target is a dragon, this trait costs 1 charge instead.

Wyvernsting: After hitting an attack, you may expend 1 charge, magically empowering the bowstring with a vile poison. If your next attack roll hits the target it must make a DC 17 Constitution saving throw, taking an additional 3d6 poison damage. If the target is a dragon, it then becomes poisoned.

Scaleshot: As a bonus action you may expend 2 charges to gain advantage on all attack rolls against a dragon for the next minute.

Proficiency with a Longbow allows you to add your proficiency bonus to the attack roll for any attack you make with it.
