Stonebane Dagger
Weapon (simple, dagger), Uncommon

This dagger was masterfully crafted by artificers of the ancient Dhakaani empire to combat the minions of the daelkyr Orlassk. It is forged from byeshk, and does not corrode or weather with time.

Although stonebane weapons are not inherently magical, this dagger ignores Resistance to nonmagical Bludgeoning, Piercing, and Slashing damage when used against creatures made of stone, creatures with stone-like natural armor (such as Gargoyles), and Petrified creatures.

As with other byeshk weapons, this dagger is especially effective against Aberrations. Whenever you hit an Aberration with this weapon, the target takes an extra 1d6 damage of the weapon’s type, and it can’t regain Hit Points until the start of your next turn.

Finesse. When making an attack with a finesse weapon, you use your choice of your Strength or Dexterity modifier for the attack and damage rolls. You must use the same modifier for both rolls.

Light. A light weapon is small and easy to handle, making it ideal for use when fighting with two weapons.

Range. A weapon that can be used to make a ranged attack has a range in parentheses after the ammunition or thrown property. The range lists two numbers. The first is the weapon's normal range in feet, and the second indicates the weapon's long range. When attacking a target beyond normal range, you have disadvantage on the attack roll. You can't attack a target beyond the weapon's long range. 

Thrown. If a weapon has the thrown property, you can throw the weapon to make a ranged attack. If the weapon is a melee weapon, you use the same ability modifier for that attack roll and damage roll that you would use for a melee attack with the weapon. For example, if you throw a handaxe, you use your Strength, but if you throw a dagger, you can use either your Strength or your Dexterity, since the dagger has the finesse property.

Byeshk Weapons

Byeshk is a rare and heavy metal of lustrous purple, mined from the Byeshk and Graywall Mountains along Droaam’s borders. Aberrations tied to the daelkyr—including Dolgaunts, Dolgrims, and Mind Flayers—are susceptible to weapons made of byeshk alloys, making the metal highly valued to the Dhakaani, Gatekeeper druids, and others that combat Aberrations. Dhakaani weapons forged during the Xoriat Incursion were often forged from byeshk.

Melee weapons made of or coated with byeshk are not inherently magical weapons, but are unusually effective when used to fight Aberrations. Whenever you hit an Aberration with a byeshk weapon, the target takes an extra 1d6 damage of the weapon’s type, and it can’t regain Hit Points until the start of your next turn.

The byeshk version of a Melee weapon costs 400 GP more than the normal version, whether the weapon is made of the metal or coated with it.
