Saizo's Star (サイゾウの爆炎針 Saizou no Bakuen Hari, lit. Saizou's Explosive Flame Needle) is a Shuriken that is introduced in Fire Emblem Fates. Eponymously named after Saizo, Saizo's Star, reflecting the character's low tolerance for displays of weakness in others, boosts the Strength of allies located within two spaces by a substantial amount. The effect does not stack with Rally Strength. Apart from raising its wielder's Speed by 2, Saizo's Star also reduces the Strength, Defense and Resistance of enemy units post-battle.
Saizo's Star is most useful in Birthright, where the Rally Strength skill is not normally available for a great majority of units.
One Saizo's Star is granted to the player upon reaching 725 visit points in My Castle. Saizo's Stars are also gained from Castle Events in Birthright and Revelations.
- The battle model used or Saizo's star is very similar to that of the iron shuriken's, with the primary difference in their colors: Saizo's star uses a burgundy colored paint, while the iron shuriken simply uses and orangish-brown rust colored paint.
