Sampling Ammunition
Ammunition arrow, bolt
The head of this arrow or bolt is a pointed glass cylinder with a hollow core. Upon hitting a corporeal creature, sampling ammunition captures a small portion of the target's skin, blood, and flesh. The sample falls to the ground below wherever the creature was hit. This sample is sealed and magically preserved inside its chamber, although it deteriorates normally once the cylinder is opened. Sampling ammunition can't collect samples from creatures made entirely of metal, stone, or other hard substances.
Traits
An item with this trait can be used only once. Unless stated otherwise, it's destroyed after activation. Consumable items include alchemical items and magical consumables such as scrolls and talismans. When a character creates consumable items, they can make them in batches of four.
Something with the magical trait is imbued with magical energies not tied to a specific tradition of magic. Some items or effects are closely tied to a particular tradition of magic. In these cases, the item has the arcane, divine, occult, or primal trait instead of the magical trait. Any of these traits indicate that the item is magical.
