Weapon (any), legendary
You gain a +1 bonus to attack and damage rolls made with this magic weapon.
This fantastical blade is the physical manifestation of unicorn smiles, bright rainbow colors, shooting star wishes, and teddy bear giggles. A gift from the Smiling Prince of the Unicorn Clan to the Unicorn ninja Rex for bringing the rogue ninja clan Five Deadly Shadows to justice.
The weapon does radiant damage and using a bonus action can dim to the ultraviolet spectrum becoming invisible. It otherwise sheds multicoloured light in a 30 foot radius sphere.
You can use an action to cause thick, black inter dimensional bright poison to coat the blazing blade. The poison remains for 1 minute or until an attack using this weapon hits a creature. That creature must succeed on a DC 15 Constitution saving throw or take 2d10 poison damage and become poisoned for 1 minute. The dagger can’t be used this way again until the next dawn.
As a reaction immediately after being hit by a melee attack, the wielder can cause the attacker to be blinded until the end of the attacker’s next turn, unless the attacker succeeds on a Constitution saving throw against your spell save DC. Once used, this reaction can’t be used again until the wielder finishes a short or long rest.
Proficiency with a sword allows you to add your proficiency bonus to the attack roll for any attack you make with it.
