Shamir

Weapon: Survivalist Bow 

Assist: Positional Assist

Special: Moonbow / Draconic Aura 

Passive A: Atk/Spd Solo 4 

Passive B: Null Follow-Up / Lull Spd/Def 

Passive C: Joint Drive Atk / Flexible 

Sacred Seal: Swift Sparrow / Heavy Blade / Flashing Blade 

• Shamir’s most straightforward set is a simple offensive set that focuses on raising her Attack and Speed as high as possible to deal the most damage and perform follow-up attacks as consistently as possible.
• Survivalist Bow works wonders for offense; in addition to granting -1 Special cooldown, it also grants her Atk/Spd +6 if she is not adjacent to any ally and prevents enemies from counterattacking if she is not adjacent to any ally and the foe’s HP is ≥ 80% at the start of combat. -1 Special cooldown is great for activating Specials to score KOs against particularly bulky enemies, and the Firesweep effect allows Shamir to not only circumvent her poor overall bulk, but also open her B slot to options aside from Desperation.
• Thanks to Survivalist Bow’s -1 Special cooldown, Moonbow and Glimmer become 1-cooldown Specials, allowing Shamir to activate them on her follow-up attack assuming no Guard effect is active. Alternatively, Shamir can use Draconic Aura, Luna, or Deadeye in combination with Heavy or Flashing Blade.
• Atk/Spd Solo, Joint Drive Atk, and Swift Sparrow all serve to augment Shamir’s already impressive offenses. Since Shamir doesn’t need Desperation in her B slot, Null Follow-Up and Lull Spd/Def are great options. The former neutralizes effects that guarantee the enemy’s follow-up attack and prevent Shamir’s follow-up attack, making her far more consistent at attacking twice, while the latter inflicts -3 Spd/Def during combat and neutralizes pesky Spd/Def visible buffs that could prevent Shamir from performing a follow-up attack or KOing.

Weapon: Survivalist Bow / Candlewax Bow+ (+ATK)

Assist: Positional Assist 

Special: Blazing Special 

Passive A: Life and Death (3 or 4) 

Passive B: Special Spiral 

Passive C: Def Smoke 

Sacred Seal: Hardy Bearing / Heavy Blade / Flashing Blade 

• Shamir’s excellent 40 Attack makes an AoE spam set a great option for her. Blazing Specials deal pre-combat damage in an area before combat, with this damage being calculated as: 1.5 x (unit’s visible Atk - enemy’s visible Def).
• Shamir’s Survivalist Bow works wonders for this set, primarily because of its slightly increased Might compared to a Slaying Bow; note, however, that because AoE damage is considered pre-combat, it will be very difficult for Shamir to prevent enemy counterattacks with her bow because the condition for that effect is the foe’s HP being ≥ 80% at the start of combat. 
• The key to this set is the synergy between Survivalist Bow, 4-cooldown Blazing Specials, and Special Spiral (if using Candlewax Bow for maximum AoE damage, then Heavy or Flashing Blade is needed for this). When Shamir activates her Blazing Special, its cooldown will be at 3 (thanks to the Slaying effect of Survivalist Bow); once she attacks, it will be at 2. After combat, Special Spiral decreases the Special’s cooldown to 0, allowing it to be activated again next combat.
• Life and Death and Def Smoke are chosen to maximize the gap between Shamir’s visible Atk and the enemies’ visible Def. If using Survivalist Bow, Hardy Bearing is chosen to prevent enemies with Vantage from counterattacking before Shamir attacks, as the Blazing Special will likely drop them at/below 75% HP to activate Vantage.

Weapon: Firesweep Bow+ / Budding Bow+ (+DEF)

Assist: Positional Assist / No Assist 

Special: Deadeye / Dragon Fang 

Passive A: Swift Sparrow (2 or 3) 

Passive B: Lull Spd/Def / Poison Strike

Passive C: Time’s Pulse / Savage Blow / Distant Guard

Sacred Seal: Swift Sparrow / Poison Strike / Savage Blow

• Unfortunately, Survivalist Bow’s effects being locked behind a Solo condition makes it very unwieldy and inconsistent in Aether Raids Defense. As such, both Firesweep Bow and Budding Bow are stronger options, with the former preventing the enemy from counterattacking and the latter being a mini-Sturdy Impact; that is, granting +4 Atk/Def on initiation and preventing the enemy from performing a follow-up attack.
• Ideally, the combination of Time’s Pulse and Infantry Pulse from allies is enough to have Shamir’s Special ready on Turn 1, whether it be Deadeye or Dragon Fang. Deadeye is a very premium, but outstanding Special that not only doubles damage dealt, but also neutralizes damage reduction; given the ubiquity of Close Call, Repel, Spurn, and damage-reduction weapons and skills, this is very valuable.
• For a Firesweep set, Poison Strike and Savage Blow can be considered to turn Shamir into a chip damage machine. Otherwise, Lull Spd/Def and Swift Sparrow for her B and A/S slots respectively work wonders to grant her extra damage and follow-up consistency; visible buffs are still very common in Aether Raids Offense, making Spd/Def buff neutralization all the more valuable.
