Takumi Bow

Named Weapon not possible to Inherit.

You don't really use Fujin Yumi because of its effect. You mainly use it because it's a unique weapon and therefore has 14 Might. He also shouldn't be able to inherit Parthia because it is also a unique weapon. You could give him a Brave Bow+ because he struggles to double attack a lot of the more popular characters but that would leave him at a very poor 28 Spd leaving him open to doubles. A lot of Takumi's strength comes from his survivability and Brave Bow+ really hurts that aspect of his character. I'd just keep Fujin Yumi. Fujin Yumi's effect is pretty useless but it has good Might and no real downsides.

Parthia is exclusive to Jeorge so it can't be given to Takumi. In the majority of situations Fujin Yumi is the best bow that Takumi can have equipped.

Archers seems to be weak and Taco is the strongest one. If Taco can't do it, no one else can.

+10 Camilla mage is a thing though.

+10 Camilla mage with gronnraven + triangle adept can actually survive at 54 atk brave bow (my +10 Taco with + atk / -hp) and proceed to one hit KO the attacker.

Let that sink in for a bit.

That is 47 attack + 1 from seals + 6 from Deadly Blow 3 for 54 attack x2

This a 54 at taco into a raven triangle camilla. Behold an archer dying to a flyer, while initiating from 100 to 0.
