Berserker Axe, +2 > Spear of Backbiting

Giving:

Berserker Axe +2
Weapon (battleaxe), very rare (requires attunement)
The battleaxe has a blade of bronze, and the haft is wound with snakeskin wrappings. The weapon detects as magical. It casts an ominous shadow in the shape of what appears to be a withered arm.
Concealed beneath the wrappings around the handle is a parchment containing the spells passwall, burning hands, and gust of wind. When the attuned wielder uses an action to say the correct words of power, which are engraved in Olman on the axe blade, one of these spells can be cast.
The axe has 12 charges and regains 1d6 + 4 expended charges daily at dawn. Casting a spell from it takes a number of charges equal to the level at which the spell is cast (5th for passwall, 2nd for gust of wind, and 1st or higher for burning hands; spell save DC 15). If the parchment is removed from the axe, the axe loses the capability of casting these spells forever.
You gain a +2 bonus to attack and damage rolls made with this magic weapon. In addition, while you are attuned to this weapon, your hit points maximum increases by 1 for each level you have attained.

Receiving:

Spear of Backbiting
Weapon (spear or javelin), very rare (requires attunement)
You gain a +2 bonus to attack and damage rolls made with this magic weapon. When you throw it, its normal and long ranges both increase by 30 feet. and it deals one extra die of damage on a hit. After you throw it and it hits or misses, it flies back to your hand immediately.
Curse. This weapon is cursed, and becoming attuned to it extends the curse to you. Until the curse is broken with Remove Curse or similar magic, you are unwilling to part with the weapon, keeping it within reach at all times. In addition, you have disadvantage on attack rolls made with weapons other than this one.
Whenever you roll a 1 on an attack roll using this weapon, the weapon bends or flies to hit you in the back. Make a new attack roll with advantage against your own AC. If the result is a hit, you take damage as if you had attacked yourself with the spear.
