|In essence, this build is similar to the current Melee Bruiser build. However, rather than use Swordbreaker to earn free hits on Mia, Arya, and other popular Swordies like Elincia and Ryoma, Desperation and Life and Death are run to quickly get Ogma into a range where he can activate Desperation and start ORKOing targets. Moonbow paired with a Wo Dao+ refined with a Speed upgrade gives him a nice and blistering 45 Speed, ensuring targets that aren't buffed guaranteed will not double him (unless a niche build like A slot Speed +3 Seal Speed +3 Mia, for example), and he doubles most units in the game. A refined weapon also gives +5 HP, making Panic Ploy the strongest seal he can equip, debuffing enemy Armor Emblem, Flier Emblem, and Horse Emblem teams through their own buffing effects; 52 HP is hard to rival.
Life and Death or Fury is a choice of survivability. Do you appreciate Life and Death's extra Speed increases and no immediate health chipping, or do you want to be able to attack targets with constant buffs to everything, including his pathetic Resistance, while chipping at your own HP to get you into Desperation range? Desperation makes or breaks the build, wherareas other builds may leave you open to attacks inbetween hits or, in the case of Brave builds, not having as much power as you may want them to have, Desperation Wo Dao lets you attack twice, and very likely proc Moonbow, not only cutting the target's Defense, but then stacking 10 damage on top of that. If you're desperate for initiation damage, Death Blow is also a viable alternative for the A slot, but Brave builds do Death Blow more justice.
The C slot is really the only other remaining slot left, and Threaten Defense works well for weakening targets around Ogma. However, if you are running a primarily Infantry team, Infantry Pulse is viable from a Dorcas or Xander's Summer variant (if you still are carrying him around) to buff the remaining members of a team. If you have neither of these, a generic Spur or Hone also works. Whatever floats the team's boat is what Ogma is prepared to use.
