"E" Units
| Estra | Stars | Tier: 3 Ascension: ❌ | Rationale |
 | Can Stop | ⭐⭐⭐ | Increases her conditional trait damage from 30% to 60% and NRG depletion from 1 to 2 |
| Preferred | ⭐⭐⭐⭐⭐ | Aside from stat/damage increases, the addition of reducing the cooldown of class skills by 1 allows her to use her second potion the next turn |
| Role/Faction |    Physical ST DPS |
| Reasoning | A simple design however she has an unparalleled DPS ceiling when the conditions of the stage are favorable. Her position is cemented by the fact she is difficult to replace when she can express her full potential. Her conditional requirements and ST playstyle however makes her somewhat unsuitable for general play, as at most she can only take down 2 units and expend 4 NRG if available to spend. While her tendency to aim for the weakest enemy may seem favorable, in some cases this can result in her jumping deep behind enemy lines and getting herself killed. Unfortunately there are currently not many stages where her strengths can be adequately expressed. She will likely remain a unit suited for investment for players looking to score highly in endgame modes, however her limited versatility and increasingly more options for physical damage makes her a unit you would prefer to off banner than pull if you already have alternate sources of DPS such as Tristan. Update-11/8/25 at the time of writing this she has fallen off the face of the earth and is only a nrg steal unit -Dio |
| Strengths | Weaknesses |
| ST DPS vs mage type units to date (320%mod on ult plus 30% DMG dealt and 20-40% P.atk with potion. Tanky against magic attacks Good A.I if autoing a stage against weaker enemies Can ignore enemy PHY shield Very low star friendly 1-4* Potions which last 3 turns. 1 will boost her P.atk based conversion by giving her more M.def which in turns gives more shields. The other will give her 45% more crit and life steal. Both will recover 1 nrg on use. Very high nrg steal up to 3-5 points per turn. | Requires enemy to have higher M.atk than P.atk and to have 3 NRG missing to deal maximum damage Specializes purely in ST, and therefore struggles in mobbing Potion are a one time use, and have debuff penalties when it expires |
| Skills | Reasoning | |
| Rank 11 |  No Restraints | Her ultimate and primary bossing skill and ignores reaction |
| Rank 9 |  Spine Pierce | Better damage, ignores shields and synergizes well with Blinding Strike. Lifesteal is redundant since we get it from potion already |
| Rank 7 |  Potion | Both potions contribute significantly to DPS. No reason to take Stance of Exorcism as the potion already provides a M.shield |
| Rank 5 |  Shadow Evasion | Fantastic reaction that disrupts an enemy turn and deals solid damage |
| Rank 3 |  Shadow Step | Shadow step is an important utility skill to remove 2 NRG prior to bursting in some cases |
| Rank 1 |  Thunder Arrow | Contributes solidly to DPS, removes NRG, and silences + blocks NRG regen |
| Loadout | Skills | Notes |
| General |  | Estra in general play is able to kill 2 targets per turn thanks to her Blinding Strike skill that allows her to act again if an enemy is defeated |
| Boss |  | While in general circumstances you start off with the Blood of Phantom Shift potions, if you already have sufficient crit chance it may be more effective to start off the round with Water of Exorcism to get the maximum attack at the start |
| Boss 2 |  | In bosses, if you lack a 5 star homa or other sources of NRG removal, replace Thunder Arrow with Shadow Step. If you are wondering why replace Thunder Arrow and bother with a separate skill for removing NRG, it is because Estra's missing NRG damage calculation is considered before an action step takes place, so the NRG removal from Trait/Thunder Arrow is not calculated. |
| Weapons | ||||
| Best |  Blade of Stratagem | Best offensive stats | ||
| Best 2 |  Void Stab | Best non-sig weapon for damage | ||
| Usable |  Newborn Blade | NBB is a good filler as its more commonly found | ||
| Trinket | ||||
| Best |  Caged Mask | Provides up to 15% ATK/DEF, making it BiS for her | ||
| Usable |  Shield of Justice | Better than hourglass, but not better than Caged | ||
| Optional 1 |  Hourglass | Great non-sig option | ||
| Tarots | ||||
| Best |  Fools | More HP means higher Magic shield values, which also means more P.ATK. Also provides DMG. However Estra may not always be able to reach maximum shield values immediately | ||
| Optional 1 |  Justice | For crit reliability | ||
| Engraving | ||||
| Best |  | For the stats | ||
| Unit/Skill/Buff Interactions | ||
| HP + Shields | Estra gains 35% of magic shield value as extra P.atk. Max shield cap scales directly HP, so increasing HP will increase shields and therefore P.atk. This makes Fools the highest damage possible. However if you can not get enough crit, you can simply run Justice. | |
| Date | Comments/Retrospection/Examination |
| Sir toffee | Below 5 stars, the cooldown delays Estra from maximizing her offensive potential early. She gains a substantial amount of P.Atk relative to her shield values, so you lose out on some potential on the first turn when you use the Blood of Phantom Shift potion. |
| Dio | Estra is able to take advantage of act again spam for OG inna and SP INNA plus saff SP by letting her spam her ult back to back to back at 5 star is why she is queen of st dps. |
| Dio | Luka/Shams dropped and they both smoke Estra in st. Shes cooked |
| Edda | Stars | Tier: 3 Ascension:✔️ | Rationale |
 | Can Stop | ⭐ or ⭐⭐⭐ | She maintains all her function as a support at 1 star, so keeping her 1 star is valid. 3 stars upgrades her assist dmg just a bit more for those st scenarios so she doesn't feel like dead weight |
| Preferred | ⭐ | Capable of fulfilling her duties as a buffer and a debuffer for magic teams at 1 star |
| Role/Faction |    Magic Team Support/ Sub DPS |
| Reasoning | Edda remains the premier support for magic damage based teams due to her unique Liquor debuff(-150 speed,-40% M.def that stacks with -M.Def debuff) that also overrides other potentially detrimental tiles and can manipulate spd of both your allies and enemies, enabling strategies otherwise impossible. Her box can be thrown into shallow water, destroying it when the enemy stands on the box leads to instant death even for bosses. She is also capable of contributing a respectable level of DPS herself through her Assist attacks. However due to her low speed and various conditions/limitations of her kit, she sits at the bottom of Tier 2. |
| Post Ascension | Edda can now become a magic dps which helps her benefit from her wine debuff when equipped. She no longer has to run [Guiding Gleam] to get DMG 3 she could just run and take arms instead which boost her dps and gives nrg as well. Moreover her trait now stockpiles left over assist procs to the next turn up to 4 times for a total of 8 assists which can be used on a horn turn for min max dps. |
| Strengths | Weaknesses |
| Liquor is a unique debuff that stacks with -M.Def2 debuff and is currently the only source you can apply it to. It can also be used to overwrite detrimental tiles, slow enemies to get an effective extra turn from warhorn or slow allies to make sure they act at optimal time Capable of outputting respectable damage herself Large AoE DMG3 from “Guiding Gleam” Box provides Highland(15% Atk) for non-AoE attacks from units standing on it. Box can be used to insta-death boss enemies on maps with shallow water. Complete support from 1* Can use bow of martyrs on st unique 10% dmg taken on target | Low speed means she can not buff dps turn 1. Needs high stars to be an effective sub DPS and must waste a turn to buff it even further Outside of min max sets up edda won't see any use in general teams because of her poor speed and assisting dmg |
| Skills | Reasoning | |
| Rank 11 |  Take Arms | AoE NRG and one turn of solid damage is useful |
| Rank 9 |  Dispelling Strike | Applies from her assists and is one method of removing buffs from enemies. It is common for later/stronger enemies to be buffed |
| Rank 7 |  Barricade Fight | Barricade has good follow up synergy with her Fortification box. P.def2 is also fairly easy to apply and should not be attempted to be applied unreliably from a support who ideally wants to build for her utility in most cases |
| Rank 5 |  Shelter Advantage | Edda is slow and in the backline, it's preferred to keep her from being hit. 40% DR is also quite substantial and easy to proc with her own Box |
| Rank 3 |   Guiding Gleam Wine Barrel Casting (castalia) | DMG3 for 3 turns is fantastic meanwhile Wine Barrel is BiS debuff for magic teams/dps and a speed manipulation tool. Get both |
| Rank 1 |  Fortification | Box provides Highland (15% Attack with ST attacks) and can be used to block movement and thrown into shallow water. Shield break is niche |
| Loadout | Skills | Notes |
| General |  | Focused primarily on Buffing and dealing dmg |
| Boss |  | Box provides Highland(15% Atk) for non-AoE attacks from units standing on it. |
| Weapons | ||||
| Best |  Longbow of the Martyr | Applies a 10% increased damage taken debuff for the team on turn st hits | ||
| Best⭐ |  Irian Combat Bow | Majority of Edda’s damage is offturn, making this the best for DPS | ||
| Optional 1 |  Megamelee Crossbow | Not as good as Combat Bow due to range falloff | ||
| Trinket | ||||
| Best |  disaster bottle | BiS for the support role. Can apply -M.DEF2 randomly to help amplify magic damage | ||
| Optional 1 |  Book | Edda is too slow to utilize this for speed manipulation reasons, but it can grant buffs | ||
| Best for dps ⭐ |    Memory of Teeth/SoJ/Hourglass etc | Classic filler for stats and stat stick works | ||
| Tarots | ||||
| Best |  Judgement | Adds another source of damage amplification for the team alongside Longbow of Martyrs | ||
| Optional 1 |  World | The cooldown reduction helps Edda cycle faster to get her core abilities back sooner | ||
| Best for dps |   Hiero/Justice | Best dmg boosting tarots for her | ||
| Engraving | ||||
| Best |  | Resets the cooldown of an ability and conserves some NRG | ||
