Legendary Dimitri

Weapon: Areadbhar

Assist: Positional Assist

Special: Noontime / Moonbow

Passive A: Distant Counter / Distant Foil

Passive B: Atrocity / Null Follow-Up

Passive C: Joint Drive Spd / Joint Drive Atk / Panic Smoke / Pulse Smoke

Seal: Spd/Res Solo / Atk/Def Solo

• By giving Dimitri Distant Counter in his A slot and increasing his Speed, he can become a formidable tank on either phase. With Areadbhar granting him Speed-based damage reduction, Dimitri's best option is to raise his Speed stat by as much as possible to reduce his Enemy Phase damage so that he can heal back up with a potent Noontime, enhanced by the damage from his Atrocity B slot.
• While Atrocity is a potent skill, a particularly deadly Legendary Dimitri will instead equip Null Follow-Up to prevent opponents from doubling him via their skills. This makes improving his Speed even more lethal, as he can survive single hits from enemies like Yune or Bramimond or, appropriately, Brave Edelgard once he is sure that they won't double him. The ability to take Null Follow-Up is the main advantage that Legendary Dimitri has over Brave Dimitri.
• Odd Tempest is an interesting skill, but does not directly affect his single combat potential, and so his C slot is free to take a Joint Drive skill, which can buff his Speed or Attack even further. Conversely, if swapping out Atrocity for Null Follow-Up, then Pulse Smoke is the obvious C slot of choice.

Weapon: Areadbhar

Assist: Positional Assist

Special: Galeforce

Passive A: Atk/Spd Solo / Distant Counter

Passive B: Atrocity / Null Follow-Up

Passive C: Odd Tempest / Time's Pulse

Seal: Heavy Blade or Flashing Blade / Atk/Spd Solo

• Legendary Dimitri comes right out of the box with a few tools to give him a lethal Galeforce build. The most obvious is his default Odd Tempest, which grants him unparalleled 3 tile movement and allows him to move through forest tiles, so long as the turn counter is at an odd number. This works similarly to Duo Ephraim's Duo Skill and allows Dimitri to close gaps between his foes.
• Atrocity takes this a step further by debuffing the opponents around his target, which allows Dimitri to pick up a second kill. However, Atrocity's damage output may actually prevent Dimitri from activating Galeforce by overkilling his foe, leaving Dimitri open and unable to move throughout the enemy turn. Luckily, the debuffs he inflicts with Atrocity can help him tank during the Enemy Phase, but you may want to consider inheriting Distant Counter into his A slot just for a little more defense if this happens often.
• Alternatively, you can replace Atrocity with Null Follow-Up, which reduces Dimitri's damage output slightly in order to ensure that he he won't be blocked by follow-up denial.
• Atk/Spd Solo is another fantastic skill for his A slot - since he'll be moving around the battlefield between Galeforce activations, Dimitri will likely be isolated and have the full effects of the buffs, further enabling him to reach the stat checks necessary for Heavy or Flashing Blade.
• Because Areadbhar has a Slaying effect, Dimitri only needs to activate Heavy or Flashing Blade in two hits in order to activate Galeforce. If he takes Time's Pulse in his C slot, the Special is reduced to 3, which means that Dimitri can take Atk/Spd Solo in his seal slot if he then attacks a foe who can retaliate and defeats them on the second hit.
