Anadar's Blade

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

You gain these benefits while attuned to this weapon:

• You gain proficiency with longswords, if you are not already proficient.
• You can attack twice, instead of once, whenever you take the Attack action on your turn. If you already gain this benefit from another source (i.e. Extra Attack), the effects do not stack.
• On a hit you deal an extra 2d6 slashing damage.
• This weapon has the finesse property.
• Attacks made with this weapon bypass resistance to slashing damage. 
• Your attunement to this weapon only ends if you choose to end it, or you die.
• You can use a bonus action to instantly summon this weapon to your hand, so long as it is on the same plane of existence. If you do not have a hand free, it drops to the ground at your feet.
• You can store up to 3 spells, that require an attack roll, in this weapon. As an action you can release a stored spells energy. When you do so, make a melee weapon attack roll with this weapon. On a successful hit, you discharge a stored spell's energy and deal an additional Xd10 damage. (X equals the stored spell's level) The damage type dealt is determined by the stored spell. On a miss the spell's energy is expended and nothing happens. 

"Hailed as Anadar's greatest work, this sword has been passed down from master to apprentice for generations. All other warlocks covet this blade, some even going so far as to attempt to either steal it or slay its current owner. Unfortunately for them, any owner of this blade is no easy foe. Any who have attempted have perished in the act. Legend has that this blade longs to be reunited with Anadar's other items."

*If you are attuned to Anadar's Blade, Anadar's Circlet, and Anadar's Robe, your number of warlock spell slots is doubled.

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