The Caltrop (まきびし Makibishi) is a Shuriken that is introduced in Fire Emblem Fates. Apart from raising its wielder's Speed by 2, the Caltrop reduces the Speed, Defense and Resistance of its target by a substantial amount upon successful striking. The Caltrop does, however, induce its wielder to suffer Strength and Skill penalties post-battle.
Unlike other Shuriken, the Caltrop is limited to a range of 1. It makes up for its lack of range with having the best speed, defense, and resistance debuffs in the game by a considerable margin.
The Makibishi is the Japanese version of the caltrop. It is believed that they were among the tools utilized by Ninjas. They were designed to be able to puncture the Waraji sandals commonly worn in Feudal Japan.
