|Move over Bridal Cordelia, there’s a new Brave Bow user in town. Takumi shares the same offensive baseline as B!Cordelia at 35/35, however, he becomes the significantly better option when you account for flier buffs.
For IVs, we go with an Attack or Speed boon to boost his strengths, and a Defense or Resistance bane as his defenses aren’t anything to brag about. While an HP bane may work as well, it will also lower his Arena BIN so be careful.
Weapon: Brave Bow+ is a fantastic choice as he has the attack and speed needed to quad and deal significant damage. While he can kill most units in PvE with just the first two hits, he has the back up of the other two to rely on.
Assist: His assist is flexible, however I tend to put Draw Back on my glass canons so they can retreat behind a tank. If you are using a dancer, (Flying Azura or Ninian highly recommended!) a positioning skill will help get takumi in and out without taking a single hit.
Special: You can use Luna or Draconic Aura. While Draconic aura will give him around 15 more damage, Luna is better in my opinion as it helps him win match ups against bulkier units. A 3 turn cooldown is preferable to a 2 turn cooldown as they will both activate during the second round of hits, so it is better to aim for higher power.
A Passive: Life and Death 3 is used to patch up the deficits created by Brave Bow.
B Passive: Desperation 3 will allow him to quad without retaliation should he take a hit.
C Passive: Fortify Fliers or any other flier buff works well when running him on a flier team, however, like most units, the C slot is more for the other members of the team
Sacred Seal: Speed +3 or Attack +3 is used to help boost his stat line. I recommend going for the seal that is the opposite of the boon you have. For example, if you have a speed up Takumi, I would give him an Attack +3 Seal.
Overall this is a player phase wrecking ball that very few units can deal with. While more heavily built meta characters counter him, making him less effective in arena, he will be able to carry any team through Tempest Trials or Chain Challenge.
