[Other] Weapon - Long-Winded Great Axe

This weapon was one of the first items to show up in my home campaign. It was first envisioned 3 years ago and had nothing more than the pun and the propensity for a character to spew often unrelated or useless information.

Originally forged as a vessel for a pirate's soul, this axe now exists as a simple sentient weapon without a living body. Two ribbed blades made of a turquoise steel, cut like a scallop shell, sprout from this axe's weeded, gnarled handle.

Long-Winded Great Axe
Weapon (great axe), uncommon

This magic weapon has 3 charges and regains 1d3 expended charges daily at dawn. When you take the attack action, you can expenda charge and replace one of your attacks with a fan sweep of the weapon. A line of strong wind 5 feet wide and 20 feet long extends from you in a direction of your choice. Each Medium or smaller creature in the line must succeed on a DC 15 Strength saving throw or be pushed up to 15 feet in the direction of the line. If a creature is within 5 feet of you when it fails this save, it also takes 1d6 cold damage. Medium or smaller objects are also pushed by the wind this way. 

Sentience. Long-Winded Great Axe is a sentient chaotic neutral weapon with an Intelligence of 9, a Wisdom of 13, and a Charisma of 16). It has hearing and normal vision out to a range of 120 ft, and communicates audibly in a loud braggadocious voice such that creatures within 60 feet of it can hear it. It can read, speak, and understand Common.

A pirate captain named Phaedrus Highcrow resides in this axe and always has a story to tell, earning him the nickname of the Long-Winded Bard of the Topaz Sea. After succeeding in achieving immortality (in a sense), he is content to tell boisterous and greatly exaggerated tales of his accomplishments whenever he is drawn, and offers grating commentary on the wielder's combat ability.
