This unique +2 katana has a non reflective transparent white blade with a misty hamon, a ghost engraved on both sides of its Habuki, and a headless samurai surrounded by clouds carved and its Tsuba. Although it's Saya and Tsuka look more like fog then anything else, and or both wrapped in the finest of white silk. When not drawn however, the katana is invisible and cannot be located with either magical or non-magical means by anyone not attuned with the weapon, as its stored in its own demiplane. If no one is attuned to the weapon or its user dies it appears as a misty silhouette wherever it's placed or its wielder falls. 

The katana improves your wisdom score by two and intelligence by one but at the cost of one from your strength, and you can speak telepathically to any creature you can see within 60 feet of you. Your telepathic utterances are in a language you know, and the creature understands you only if it knows that language. Your communication also gives the creature the ability to respond to you telepathically.

You gain access to yokai points and have 7 yokai points.  You regain all of your Yokai points every day at dusk. 

You can cast misty step (2nd lvl/1 point), invisibility( 2nd lvl/1 point), greater invisibility(4th lvl/ 2 points), and Etherealness(7th lvl /5 points, 8th lvl/7 points). You may also gain the benefits of a short rest for 1 point or a long rest for 3 instantly(if YK points are used for long rest it negates your need for sleep)

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