Thea

Weapon: Icy Maltet (+Eff)

Assist: Positional Assist

Special: Bonfire 

Passive A: Atk/Def Unity

Passive B: Guard Bearing / Mystic Boost / Quick Riposte 

Passive C: Rein Skills

Sacred Seal: Atk/Def Solo / Mystic Boost / Quick Riposte

• With no innate Distant Counter and a weakness to Bows necessitating Iote’s Shield, Thea’s best competitive set is a melee specialist one; this role is paired with a Far Save Armored ally that can take ranged attacked for Thea, allowing her to focus on optimizing combat against melee enemies. Icy Maltet is what makes this set particularly viable for Thea, as it alone grants +21 Atk/Def and a Guard effect during combat.
• This set frees Thea’s A slot from a Distant Countering skill and her Sacred Seal from Iote’s Shield, allowing her to invest these slots into her stats or other effects. As most melee enemies deal physical damage, this set focuses on maximizing Thea’s Atk/Def (which makes Bonfire an ideal Special for her, as it has a lenient 3 cooldown and increases damage by 50% of Thea’s Def when activated).
• In addition to granting +5 Atk/Def if Thea is within 2 spaces of an ally, Atk/Def Unity also reverses visible Atk/Def debuffs and panicked Atk/Def buffs during combat, making it her strongest A slot choice.
• Thea has a variety of B slots to choose from, each with their own merits:
  • Guard Bearing grants 50% damage reduction on the first attack Thea takes on Enemy Phase. Since the AI prioritizes units that deal the most damage, this damage reduction will usually apply to the attack that Thea would take the most damage from, making Guard Bearing a viable option despite its specificity.
  • Mystic Boost heals Thea for 6 HP after combat, granting her some minor sustainability.
  • Quick Riposte allows Thea to perform a follow-up attack if she is initiated against and her HP is ≥ 70% at the start of combat, allowing her to break through follow-up prevention.
• Rein skills inflict -4 to two stats on enemies within two spaces of Thea during combat, improving the combat performance of both Thea and her allies (most notably, her Far Save ally).
• Since Savior skills can take hits for allies from two spaces away, Thea can safely use Solo skills such as Atk/Def Solo, which grants +6 Atk/Def during combat if Thea is not adjacent to an ally. Alternatively, she can use Mystic Boost or Quick Riposte if not using them in her B slot.

Weapon: Icy Maltet (+Eff) 

Assist: Dual Rally+ or Rally Up+ Skills / Positional Assist

Special: 500 SP Specials

Passive A: B Duel Flying 4 

Passive B: Aerobatics / Flow Skills / Near Trace Skills / Flexible

Passive C: Rein Skills / Ground Orders / Flexible

Sacred Seal: Atk/Spd Solo / Guidance / Aerobatics / Flexible

• Thea is a premier max-investment Arena project, as her 3-4* rarity allows her to be easily merged up (which contributes to higher Arena score) and she is notably stronger than many other 3-4* options thanks to Icy Maltet’s effective +21 Atk/Def, +9 Def/Res, and Guard. This set focuses on maximizing Thea’s Arena score.
  • For every 100 SP a unit’s skills cost, their Arena score increases. Because Thea lacks access to a 300 SP B slot, the maximum SP her skills can cost in total is 2380 SP; as she cannot reach 2400 SP, players just need to make sure Thea’s total SP cost is ≥ 2300.
• Dual Rally and Rally Up Assists are ideal because of their 400 SP cost, though positional Assists can still be used if players are willing to sacrifice a bit of scoring for better mobility and easier Arena runs.
• The combination of the ubiquity of Special-slowing effects and Thea’s inability to accelerate her Special trigger or grant herself additional Special charge makes her Special choice relatively unimportant. All that matters is that she has a Special that costs 500 SP.
• B Duel Flying 4 is a necessity, as it treats Thea’s BST as if it were higher in Coliseum modes (higher BST means higher Arena score).
• The rest of Thea’s skills are mostly up to preference; some options will be listed below. Just be sure that Thea’s B, C, and S slots sum to 700 SP.
  • B:
    • Aerobatics (Mobility)- Allows Thea to teleport to spaces adjacent to non-Flier allies within two spaces
    • Flow Skills (Combat)- All neutralize effects preventing Thea’s follow-up on initiation; Guard inflicts Guard effect, Refresh heals 10 HP after combat, Flight has true damage and damage reduction locked behind Spd/Def checks
    • Near Trace Skills (Combat/Utility)- Inflict -3 to two stats on enemy during combat, in addition to allowing Thea to use her remaining movement plus one additional space to move after her first combat, structure destruction, or Assist use
  • C:
    • Rein Skills (Combat/Utility)- Inflict -4 to two stats on enemies within two spaces during combat
    • Ground Orders- Grants status to adjacent, non-Flier allies at the start of the turn that allows them to teleport to spaces adjacent to non-Flier allies within two spaces
  • S:
    • Solo Skills (Combat)- Grant +6 to two stats during combat if Thea is not adjacent to an ally
    • Guidance- Allows Infantry and Armored allies within 2 spaces to teleport to spaces adjacent to Thea
    • Aerobatics

Weapon: Icy Maltet (+Eff) 

Assist: Positional Assist 

Special: Moonbow / Noontime 

Passive A: Distant Countering A Slot 

Passive B: Flow Skills / Near Trace Skills / Mystic Boost

Passive C: Rein Skills 

Sacred Seal: Iote’s Shield / Solo Skills / Mystic Boost

• The combination of Thea’s remarkably well-balanced statline and Icy Maltet’s effective +21 Atk/Def, +9 Spd/Res, and Guard during combat make her a strong generalist that can play her part on both Player Phase and Enemy Phase.
• Low-cooldown Specials work best for Thea, as the only way she can gain additional Special charge reliably is through allies (such as Brave Lucina, New Year Velouria, and Summer Hilda). Moonbow serves as a damage increase via ignoring 30% of the enemy’s Def, while Noontime grants sustainability via healing 30% of damage dealt.
• Distant Countering A slots such as Distant Stance, Distant Dart, and Distant Counter are key for this set, as Thea’s Enemy Phase reliability drastically decreases if she cannot counterattack against ranged enemies (if she has a Far Save ally, she should just be using a melee specialist set instead).
• Thea has a variety of B slots to choose from, each fulfilling different roles.
  • Flow skills neutralize follow-up prevention on initiation in addition to providing supplementary effects (Guard effect for Guard, 10 HP after combat for Refresh, and true damage and damage reduction locked behind Spd/Def checks for Flight).
  • Near Trace skills inflict minor stat debuffs during combat and allow Thea to move her remaining movement plus one space after her first combat, structure destruction, or Assist use.
  • Mystic Boost heals Thea for 6 HP after combat and disables Wrathful Staff, an effect that allows Staff units to deal normal damage rather than halved.
• Rein skills are useful for Thea as always, inflicting -4 to two stats on enemies within two spaces during combat to support both herself and allies.
• Iote’s Shield neutralizes Flier-effective damage, making it vital for tipping the scales against enemies with Flier-effective weaponry. Alternatively, she can use Solo skills to increase her stats if she’s not adjacent to an ally or the aforementioned Mystic Boost.
