Serpent's Tooth 2014
Weapon, uncommon, (requires attunement)
When you hit with an attack using this magic spear, the target takes an extra 1d6 poison damage. In addition, while you hold the spear, you have advantage on Dexterity (Acrobatics) checks.
Properties
Thrown (range 20/60)
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.
Versatile (1d8)
This weapon can be used with one or two hands. A damage value in parentheses appears with the property—the damage when the weapon is used with two hands to make a melee attack.
