Switchscythe
1d6P·Advanced·Pick·One-handed
Another complex gnome invention, the switchscythe is designed for versatility. The curved blade is partly hollow, containing a long rod of wood or metal; the rod can be pulled perpendicular to the blade, turning the switchscythe from a sweeping, axe-like blade into a hooked pick capable of grappling a foe.
Traits
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.
A creature with this trait is a member of the gnome ancestry. Gnomes are small people skilled at magic who seek out new experiences and usually have low-light vision. An ability with this trait can be used or selected only by gnomes. A weapon with this trait is created and used by gnomes.
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.
The weapon viciously pierces the target, who takes 2 additional damage per weapon damage die.
