Item: Tricky Pick

Backstabber: When you hit an off-guard creature, this weapon deals 1 precision damage in addition to its normal damage. The precision damage increases to 2 if the weapon is a _+3 weapon_.

Fatal: The fatal trait includes a die size. On a critical hit, the weapon’s damage die increases to that die size instead of the normal die size, and the weapon adds one additional damage die of the listed size.

Kobold: A creature with this trait is a member of the kobold ancestry, reptilian humanoids who are usually Small and typically have darkvision. An ability with this trait can be used or selected only by kobolds.

Modular: The weapon has multiple configurations that you can switch between using an Interact action. Typically, switching between configurations of a modular weapon allows it to deal different types of damage (listed in the trait, such as “modular B, P, or S”), though it's possible for a modular weapon's description to list more complicated configurations.
