Jabi

Jabi are a specialized and varied class of weapons, many of which are designed by The Brass Knot.

Those who wish to hunt monsters must eventually come to the realization that many of their most tried and trusted weapons were designed for fighting humanoids and fall short when used against creatures that are large, flying, armored, or some combination of the above. While spears and pole-arms are usually serviceable against monsters, specialized weapons are called jabi, originating from the old gnomish word for "hunter."
 * Buri: Sometimes called "bleeders," these are the most common Jabi. They are a polearm with an oblique slicing blade designed not to get stuck in flesh and open surface wounds. Notably less unwieldy than a pike, Buri are two-handed pole-arms dealing 1d10 base damage.  They are finesse weapons.
 * Kirufi: "Scale-Peelers," are designed to hook under scales or plates of armor and pull them up, dealing considerable damage in the process. Featuring  a short handle attached to a flat hook with a serrated blade on the outside, a kirufi may bypass natural armor, dealing 1d8/1d10 base damage as a one/two-handed weapon.  The Kirufi is much less effective against humanoid foes, dealing 1d6 damage.
 * Bekkopi: Often referred to as "four-handers," bekkopi are designed to be used by two warriors working in concert to pierce thick shells and scales. Essentially an oversized war pick, a Bekkopi deals 2d6 damage plus the combined strength modifiers of the wielders and ignore most armor.  However, a Bekkopi is incredibly unwieldy at close range or against smaller foes.  Both wielders must be proficient in the weapon to apply the bonus and either wielder may make the attack roll.
 * Ochiku: Called "Fall-Hooks" ochiku are designed to aid in combat with flying creatures. Ochiku are two-handed reach weapons dealing 1d6 damage. A medium or smaller creature hit by an ochiku may not move more than 10 feet awy from the weilder within the next round without making a combative strength or dexterity check.
 * Tirud: "claw-shields" are only slightly different from other large shields and in truth anyone familiar with the technique can easily reproduce the effect using any tower shield. A character proficient with Shirud may use a tower shield or a shirud to gain +2 AC against large, sweeping attacks and has advantage on rolls to resist being pushed or forced back due to such an attack.
