The Axe Splitter (斧斬りの刀 Ono kiri no katana, lit. Axe Cutting Katana) is a Katana that is introduced in Fire Emblem Fates. Like its name suggests, the Axe Splitter is capable of inflicting effective damage (3x its base weapon might) against Axe and Club-wielding enemies; however, it is ineffective against non-axe or club wielding enemies, dealing 4 less damage against them and suffering a -10 penalty to hit rate. Similar to most other Katana, the Axe Splitter reduces its wielder's Defense and Resistance by 1, but raises their Speed by 1.
Effective against Axes; ineffective otherwise.
One Axe Splitter is granted on all paths of Fire Emblem Fates after reaching 1,250 visit points in My Castle. In Birthright and Revelations, the Lottery Shop has a chance of awarding the Axe Splitter upon winning a good prize. The Dawn Armory in Birthright and Revelations sells a limited stock of Axe Splitters. Finally, Axe Splitters may be found on castle events and event tiles in Birthright and Revelations.
