Bahamut's Wrath

This item appears to be a platinum  longsword hilt with a dragon's head. While grasping the hilt, you can as a free action cause a blade of pure radiance to spring into existence from the dragon's head, or make the blade disappear. While the blade exists, this magic longsword has the finesse property. If you are proficient with shortswords or longswords, you are proficient with the Bahamut's Wrath.

You gain a +3 bonus to attack and damage rolls made with this weapon, which deals radiant damage instead of slashing damage. When you hit an undead, draconic, or an evil creature with it, that target takes an extra 2d8 radiant damage.

The sword's luminous blade emits bright light in a 15-foot radius and dim light for an additional 15 feet. The light is sunlight. As an action you may channel energy to the sword (If you have the extra attack feature you may make as many attacks this way as the feature would normally allow you with an attack action). Make an ranged attack or attacks at a max distance of 60 feet as you would make a melee attack with this weapon. The sword shoots rays of pure radiant light that home in on your target.

While attuned and the item is in you possession you gain a +2 to dexterity and strength.

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