| What Kind of Character Are They? | ・Jaws of Closure ignores foes' Savior effects and inflicts 【Undefended】 on multiple foes after Elm's actions, inflicts Atk/Spd/Def/Res-5 and 50% DR shred on foes within 3Rx3C, has built-in bonus stats, up to +32 true damage, and +24 true DR on foe's first attack. ・New Opening allows easier transformation, grants bonus stats, null Guard, up to +12 bonus true damage, true DR on foe's first hit, and true DR on foe's Specials, and 7 HP post-combat healing. |
|
Might: 14 Range: 1 Accelerates Special trigger (cooldown count-1). When unit is in combat, foes' Savior effects will not trigger. After unit acts (if Canto triggers, after Canto), inflicts 【Undefended】 on closest foes within 5 spaces of unit through their next actions. For foes within 3 rows or 3 columns centered on unit, inflicts Atk/Spd/Def/Res-5 and reduces the percentage of foe's non-Special "reduce damage by X%" skills by 50% during combat (excluding area-of-effect Specials). At start of combat, if unit's HP ≥ 25%, grants bonus to unit's Atk/Spd/Def/Res= 15% of unit's Spd at start of combat, unit deals X x 8 damage (excluding area-of-effect Specials), and reduces damage from foe's first attack by X x 6 during combat (X = number of foes within 3 spaces of target, including target; max 4; "first attack" normally means only the first strike; for effects that grant "unit attacks twice," it means the first and second strikes). At start of turn, if unit is adjacent to only beast or dragon allies or if unit is not adjacent to any ally, unit transforms (otherwise, unit reverts). If unit transforms, grants Atk+2 and unit can move 1 extra space (that turn only; does not stack). |
|
Cooldown Count = 3 Boosts damage by X% of unit's Spd when Special triggers (if transformed, X = 50; otherwise, X = 40). If both of the following conditions are met, reduces damage from foe's next attack by 40% during combat: - Unit's or foe's Special is ready, or unit's or foe's Special triggered before or during this combat. - Unit is transformed or unit's Spd ≥ foe's Spd-4. (Once per combat; excluding area-of-effect Specials). |
|
If unit can transform, transformation effects gain "if unit is within 2 spaces of a beast or dragon ally, or if number of adjacent allies other than beast or dragon allies ≤ 2" as a trigger condition (in addition to existing conditions). If defending in Aether Raids, at the start of enemy turn 1, if conditions for transforming are met, unit transforms. If unit is transformed or if foe's HP ≥ 75% at start of combat, grants Atk/Spd/Def/Res+9 to unit, neutralizes effects that inflict "Special cooldown charge -X" on unit, unit deals +X damage (excluding area-of-effect Specials), reduces damage from foe's first attack by X during combat ("first attack" normally means only the first strike; for effects that grant "unit attacks twice," it means the first and second strikes), reduces damage from foe's Specials by an additional X (excluding area-of-effect Specials; X = number of spaces from start position to end position of whoever initiated combat x 4; max 12), and restores 7 HP to unit after combat. |
|
Enables 【Canto (Rem. +1; Min 2)】while transformed. If unit is transformed or unit's HP ≥ 25% at start of combat, inflicts Spd/Def-4 on foe and deals damage = 20% of the greater of unit's Spd or Def (excluding area-of-effect Specials), and also, if unit's Spd > foe's Spd, neutralizes effects that guarantee foe's follow-up attacks and effects that prevent unit's follow-up attacks during combat. |
|
Inflicts Spd/Def-4 on foe, disables skills of all foes, excluding foe in combat, and grants Special cooldown count-1 to unit before unit's first attack during combat. |

◯ = Stat gains +4 with a superboon, ✕= Stat goes down by -4 with a superbane, - = No assets or flaws
| See the IV Checker for All Units | Trait Fruits—How to Change IVs |
When using an Ascendant Floret, we recommend getting the next superboon if it fits the hero. If not, consider what stat your hero needs most.
The best IVs for Elm are +Spd and -Res. Elm's Spd is his best stat, mostly due to his bonus stats calculation from Jaws of Closure and the Null Follow-Up effect from Bestial Agility, which is his best B skill.
Elm's Res is his least important stat due to his role as a physical initiator. He will most likely be facing physical frontline units, thus reducing his Res is preferred over reducing his Def.
We recommend +Spd when merging Elm up to +10 for similar reasons above.

Elm's base kit already functions great as an offensive initiator. Emblem Sigurd ring, while somewhat redundant, improves Elm's Canto to 3 and allows him to retreat further back after bursting down a foe. Emblem Celica ring can also be used to immediately reach the enemies as well, and is the preferred ring if Elm is paired with Legendary Sakura.

Note: Stats bonuses from skills are not taken into account.
Elm is a close physical attacker (range = 1). Therefore, when not accounting for the Weapon Triangle, the amount of damage he deals will be equivalent to his Atk minus the foe's Def stat.

Elm's exclusive weapon Jaws of Closure is the main bulk of his strength as a unit, making him one of the best initiator and support hybrid units in the entire game.
When Elm is in combat, Jaws of Closure completely disables foes' Savior effects, allowing Elm to attack his intended target without interference from enemy Savior tanks.
More importantly, after Elm acts, Jaws of Closure inflicts 【Undefended】 on the closest foes within 5 spaces. The key word here is acts; Elm doesn't even need to enter combat to apply 【Undefended】 to enemy units.
Jaws of Closure also inflicts Atk/Spd/Def/Res-5 and applies 50% damage reduction piercing to foes within 3 rows or 3 columns centered on Elm. This effect allows Elm to apply additional support for his allies even from far distances, or use these effects himself to further cripple his foes whenever he attacks.
In combat, Jaws of Closure grants Elm bonus Atk/Spd/Def/Res equal to 15% of his Spd, and up to +32 bonus true damage per attack and +24 bonus true damage reduction on his foe's first attack based on the number of foes within 3 spaces of Elm.
Jaws of Closure prevents foes' Savior skills and isolates key targets, then the bonus true damage per attack combined with Elm's high Spd allows him to burst down those foes with ease.
Elm's New Opening A skill gives him easier transformation conditions and allows him to transform immediately on Aether Raids Defense.
In combat, New Opening grants Elm Atk/Spd/Def/Res+9, neutralizes effects that slow down his Special cooldown charges, up to +12 bonus true damage, true damage reduction on foe's first attack, and true damage on foe's Specials (excluding area-of-effect Specials) based on distance travelled, and 7 HP post-combat healing.
The true damage and true damage reduction effects of both Jaws of Closure and New Opening stack, giving Elm up to +44 bonus true damage per attack and +36 true damage reduction on his foe's first attack.
With Elm's ability to isolate key targets and ignore Savior effects, Elm can instantly burst down his foes, and with Elm's high Spd stat, it will be difficult to generate follow-up attacks against him, allowing his true damage reduction effects to shoulder the brunt of his foe's attacks.
As a flying unit, Elm takes 1.5x damage from bows and weapons effective on flying units. Be sure to keep them out of the range of archers and leave them to other units.

While these skills are amazing for offensive Beast units, we recommend keeping at least one copy of Elm for your use, as he is a fantastic unit.
