Nino

Weapon: Amity Blooms+ (+Spd) / Plegian Torch+ (+Spd)

• Amity Blooms makes for a very strong general option by providing a conditional significant stat boost as well as healing during combat.

• Another strong option with a higher ceiling of potential is Plegian Torch, which scales based on the amount of debuffs the foe has inflicted on them.

Assist: Reposition 

Special: Noontime / Sol / Moonbow / Ruptured Sky

• The choice between healing specials such as Noontime and Sol compared to offensive ones such as Moonbow and Ruptured Sky can be weighed depending on the amount of healing from other sources such as Amity Blooms and/or Mystic Boost

Passive A: Solo Skills / Stance Skills / Unity Skills

• Both Stance skills and Solo skills that boost Nino’s key stats have their advantages. Stance skills are exclusive to Enemy Phase but come with the added benefit of the Guard effect while Solo skills can be active in both phases with the condition of not being adjacent to any allies.
• Unity skills can be the premium options if your primary focus is Aether Raids. In addition to the simple +5 boost to the chosen stats, any debuffs and/or Panic effect inflicted on those stats will be reversed to become an in-combat buff.

Passive B: Null Follow-up / Null C Disrupt

• Null Follow-up offers exceptional utility by nullifying foe’s skill that guarantee their follow-up attacks as well as those that prevent your own. 

• Null C-Disrupt is another highly coveted skill for infantry tanks, as it allows them to retaliate against opponents that would otherwise disable any form of counterattack such as Firesweep weapon users and Dazzling Staff healers.

Passive C: Pulse Smoke / Joint Drive Atk / Flexible

• Smoke skills such as Pulse Smoke are very effective when taking on multiple opponents. Pulse Smoke is particularly effective in reducing the damage of opponents around the target after combat by slowing down the activation of their Special.
• The C slot can otherwise be replaced as needed to suit the team.

Sacred Seal: Solo Skills / Mystic Boost

• Any Solo or Stance skills that boost Nino’s key stats makes for an effective Sacred Seal option.
• Mystic Boost grants additional healing after combat as well as disabling the effects of Wrathful Staff and adaptive damage.

Weapon: Iris’ Tome (+Eff)

• Though it doesn’t really matter how you refine it, aim to easily maximize scoring potential by using Nino’s personal weapon. 

Assist: Rally Def/Res+ 

• A maximum SP rally skill, ideally containing the stats that are less important to Nino herself.

Special: Blue Flame / Aether

• Neither of these max SP skill options are exactly “optimal” on a typical offensive mage but Blue Flame can at least activate in a relatively reasonable amount of time for a good damage boost. 

Passive A: G Duel Infantry

• G Duel Infantry is the choice A slot for optimal arena scoring, as it greatly boosts Nino’s BST bin.  

Passive B: Special Spiral / Lull Skills / Quick Riposte

• As far as offensive B slot options go, both Special Spiral and Lull skills such as Lull Atk/Res make for great max SP options. 
• Though not ideal with a set like this, there are a number of max SP budget options such as Quick Riposte that can provide some combat utility. 

Passive C: Atk/Res Menace / Joint Drive Atk / Flexible

• Atk/Res Menace makes for an especially effective choice with this set by debuffing nearby foes and granting it as a buff for Nino. 

• The C slot can otherwise be replaced as needed to suit the team

Sacred Seal: Heavy/Flashing Blade / Atk/Spd Bond

• Atk/Spd Bond compliments Nino’s offensive playstyle as well as synergizing with the adjacency condition of Specials such as Blue Flame.

Weapon: Iris’ Tome (+Spd)

Assist: Reposition 

Special: Glimmer / Dragon Fang / Blazing Wind

Passive A: Atk/Spd Push / Atk/Spd Solo / Swift Sparrow / Life and Death

Passive B: Special Spiral / Desperation / Lull Spd/Res

Passive C: Times Pulse / Flexible

Sacred Seal: Life and Death / Heavy/Flashing Blade / Atk/Spd Solo / Swift Sparrow /

Weapon: Iris’ Tome (+Atk)

Assist: Reposition 

Special: Glimmer / Miracle

• Another great use of the Blade tome type weapon and another effective choice for Aether Raids is the Vantage sweeper setup.

• The choice of Special is mostly inconsequential but there is quite a bit of utility in being able to charge Miracle and having that safe extra hit against you. 

Passive A: Close Counter / Close Foil

Passive B: Vantage

• The main focus of this set is running Close Counter with Vantage. Upon hitting the HP threshold for Vantage, any subsequent opponents that initiate on Nino are forced to take at least one hit before having the chance to counterattack.
• With this combination, Nino can potentially take out multiple opponents in the Enemy Phase completely unscathed. However, the amount of support that Delthea needs in order to take out her opponent in only one hit can vary greatly depending on who she is left in the range of. Opponents with high magical bulk can be difficult to face.

Passive C: Fatal Smoke / Times Pulse / Res Smoke / Savage Blow 

• Fatal Smoke is the premium with any Vantage-centric build, as it prevents any opponents afflicted from being able to restore their HP. In particular, it stops the effects of the healing tower structure. 

• Times Pulse is particularly useful when run alongside Miracle, as it allows Nino to easily charge the Special with two hits. 

• Cheaper options such as Res Smoke and Savage Blow also make for solid options in increasing this set’s effectiveness. 

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

• Heavy/Flashing Blade are choice in getting Nino’s Special charged as quickly as possible. This is especially important alongside miracle. 
• Otherwise, any form of Attack boosting seal will make for an effective option.
