One-handed martial weapon. 1d8 slashing damage. 19-20 x2 critical. 3 lbs. 15 gp. Special: Fragile, see text
This weapon is intentionally designed to fly apart into shards that can cut your opponent. When this blade breaks while you are wielding it during combat due to an opponent’s sunder attack, you may immediately make 3 attacks as if with thrown daggers against that opponent.
Weird and wonky weapon. Requires a very specific situation, but man that would be cool!
