Master Artisan

As part of a short rest, if you have a blade such as a knife or dagger, you can harvest bone and hide from a slain creature of size Small or larger to create one of the following items: a shield, a club, a javelin, or 1d4 darts or blowgun needles. If you have a set of woodcarver's tools, you can create a greatclub, a quarterstaff, a spear, or 1d4 arrows. If you have leatherworker's tools, you can create a sling, a whip, or a net.

Alternatively, you can add spikes to an existing shield, club, or greatclub (no artisan's tools required). The spikes deal 1d6 piercing damage if you use your shield as an improvised weapon or in addition to the club or greatclub damage. If you are wielding a spiked shield and a creature misses you with a melee attack, you can use your reaction to inflict 1d6 piercing damage on it.

If you harvest raw materials from a slain aberration, celestial, elemental, fiend, or undead creature, weapons and ammunition created from it deal an extra 1d6 damage of a type indicated in the table below.
