You have a +3 bonus to attack and damage rolls made with this magic weapon.

As a bonus action, this sword can be extended gaining a reach of 10ft. This effect lasts for 1 minute or until you end it as a free action. While extended the blade gains the following benefits:

• Whenever you take the attack action you may replace one attack with the slash attack, a 10ft cone DC 17 Dex saving throw or take (2d6 + Dex slashing damage).
• You have 3 charges which recharge at dawn. You can expend one charge as an action to "Dash" in a 30ft line, causing any creature caught in the line to roll a DC16 Dex saving throw or take 2d6 + Dex slashing damage and 3d6 lightning damage, or half as much on a successful one.
• As an action you can produce a 10ft by 10ft cyclone within a 60ft area you can see. This cyclone persists for 1d4 rounds. If a creature starts its turn with 5ft of the cyclone it must make a DC 16 Strength saving throw or be pushed 5ft in a random direction and take 1d6 bludgeoning damage.
• Whenever you strike with this blade you add an additional 1d6 lightning damage and take 1d4 bleed damage, the creature must then make a DC 16 Con save or begin bleeding. While a creature is bleeding they take 1d4 bleed damage at the start of their turn, the creature can make another Con save at the end of each of its turns. If a creature is hit again and fails the con save, this bleed damage stacks and deals an addition 1d4 bleed damage at the start of that creatures turn.

This sword grants steps as silent as the wind. While attuned to this sword, you gain a +5 to stealth and you no longer leave tracks unless you want to. You can also cast feather fall as the spell at will.

Finally, you gain resistance to lightning damage and your speed is increased by 10ft.

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