Hilt of the Herald (1st Attunement)

Default Bonus: 
+1 to hit. As a free action, make a basic melee weapon attack with this weapon

Outwardly, this item appears to be the hilt taken from almost any weapon, made of a golden material. Once attuned, the user can will the hilt to project a magical liquid into the form of any weapon. The liquid appears to be flowing water to an observer, but is as hard as strong steel. You feel like you could push further into the hilt to get more out of it... 

A demonic voice whispers in your thoughts, suggesting cruel things
