Fir

• Preferred IV: +ATK / -HP
• Weapon: Nameless Blade (+Eff)
• Assist: Reposition
• Special: Iceberg / Glacies
• Passive A: Warding Breath / Steady Breath
• Passive B: Wrath / Swordbreaker / Quick Riposte
• Passive C: Def Ploy / Varies with Team
• Sacred Seal: Quick Riposte / Quickened Pulse / Close Def

One of the biggest benefits of Nameless Blade is that Fir can now easily activate Iceberg or Glacies on any given combat while still benefiting from +10 damage on Specials. There is powerful synergy between Warding Breath, refined Nameless Blade, and Iceberg - Fir can activate Iceberg immediately after being attacked once, and potentially add +20 damage on top of that (if she enters Wrath’s HP threshold after that attack). This results in massive damage retaliation, and can wipe out a huge portion of non-blue units - red or colorless enemies need 83 physical bulk to survive an unbuffed and unsupported Fir’s Wrath-powered Iceberg.

This combo gets even more potent with either the Quick Riposte of Quickened Pulse seals. Quick Riposte can allow Fir to activate Iceberg twice in a single combat if she gets doubled. Quickened Pulse allows Fir to run Glacies instead of Iceberg, resulting in a whopping 93 damage nuke, or +48 damage (Glacies with Warding Breath, refined Nameless Blade, and Wrath).

Warding Breath is key to this build, as the accelerated Special charge can result in instant Special activations. The +4 Resistance is a great benefit as well, as it further increases Iceberg or Glacies damage. Steady Breath is an acceptable alternative; although Defense isn’t quite as important as Resistance, the accelerated Special charge is the most important aspect.

Wrath is a powerful component of this set, as not only does it grant +10 damage to Specials when in the 75% HP threshold, but it also reduces the Special cooldown by 1 every turn (assuming Fir is within the HP threshold) - this can allow Fir to pull off Glacies nukes multiple times. If Wrath is unavailable, then Swordbreaker or Quick Riposte are both acceptable alternatives. The Close Def seal is a good choice if running Quick Riposte as a B skill.

Def Ploy is an excellent skill that makes great use of Fir’s strong Resistance stat - debuffing enemy Defense makes it that much harder for them to survive a Special nuke.

• Preferred IV: +ATK or +SPD / -HP or -DEF
• Weapon: Nameless Blade (+Eff)
• Assist: Reposition
• Special: Iceberg / Glacies
• Passive A: Distant Counter / Fury
• Passive B: Wrath / Quick Riposte / Swordbreaker
• Passive C: Def Ploy / Varies with Team
• Sacred Seal: Quick Riposte / Distant Def

With the introduction of Nameless Blade, Fir no longer has to choose between Slaying Edge and Wo Dao for her weapon - now she can effectively have both at the same time. The combination of reduced Special cooldown as well as +10 damage on Special activations makes her Specials significantly more potent than ever before. She can get +35 damage on a Special activation from Iceberg, refined Nameless Blade, and Wrath; this massive burst damage is a huge increase to her offensive potential.

The choice between Iceberg and Glacies is mostly dependent upon the level of available team support. With only 36 base Speed (without a +SPD boon), Fir is vulnerable to getting doubled by speedy units. If she can get Speed buffs from her team to avoid getting doubled, then Iceberg is a better choice to ensure a Special activation. Glacies is a big boost in damage, but relies either on Fir getting doubled or receiving Infantry Pulse support (if not doubled) to be able to activate.

Distant Counter is vitally important to allow Fir to safely deal with mages by baiting and killing them on the counter. Fir is particularly well suited for this, thanks to her high Resistance. On a budget, however, Fury is easily workable.

Wrath will increase the damage that Fir can deal with her specials, which are already the key to her damage output. It is best paired with the Quick Riposte seal so that Fir will be able to secure doubles against even the speediest of enemies. Otherwise, Quick Riposte can be run in Fir’s B slot, paired with the Distant Def seal. Swordbreaker is also an option if running Fury for a budget set.

Def Ploy works very well for Fir, as it allows her to utilize her high resistance stat at all times. While it is incredibly potent, it is not strictly necessary for this build, and can be changed out for any other C slot as preferred.
