The Venge Naginata (武者の薙刀 Musha no naginata, lit. Warrior's Naginata) is a Naginata that is introduced in Fire Emblem Fates. The Venge Naginata doubles its Might when used to counter attacks. Even an unforged Venge Naginata has a whopping 18 might when used in this manner, easily outclassing most other lance and naginata type weapons and being just shy of being the best in this regard (the Waterwheel has 19 might, though it is saddled with negative traits that the Venge Naginata is free from). To top it off, the Venge Naginata has a good chance to hit. However, it reduces the user's avoid by 20%.
Might is doubled when counterattacking.
