Sacred Seal: Close Def / Shield Session / Mirror Stance

Ymir is an excellent utility unit thanks to her exclusive skills. Everliving Domain grants her allies a +4 boost to Defense and Resistance and a one time Miracle effect that allows her allies within 2 spaces to survive a hit that would KO them with 1 HP as long as their HP is equal to or above 75%, while Everliving Breath heals and neutralizes any penalties on any allies within space of Ymir and a target that used a rally or movement assist skill (On top of the obligatory +5 boost to all stats during combat and free guaranteed follow-up attack).
For general use, Ymir is best suited to an Enemy Phase role, so skills such as her innate Atk/Res Unity and Mirror Stance are excellent options to bolster her stats during Enemy Phase while giving her other benefits such as debuff protection or the Guard effect.
Ymir’s innate A/R Near Trace let her hit and run more effectively, while Lull Atk/Res allows her to negate the foe’s Attack and Resistance buffs. Which one is ran is dependent on which effect one prefers.
Defensive sacred seals such as Close Def, Mirror Stance, and Shield Session are good options to fill Ymir’s sacred seal slot.

Sacred Seal: Close Def / Distant Guard / Close Guard / Drive Atk

Thanks to Everliving Domain, Ymir holds a decent niche as an AR Defense unit that can prevent foes from KO’ing her teammates before they get a chance to attack, unless the foe is capable of triggering the miracle effect in a single hit(Good luck doing this against Save Armors) or using Brave weapons to attack through the effect instead. Altogether this adds a decent amount of durability to her teammates as long as they stick together, especially when coupled with other support seals like Distant Guard and Close Guard.
AR-D A slots, particularly AR-D Def/Res 3 and AR-D Atk/Res 3 are Ymir’s best A slot options thanks to them providing more stats than other A slot skills in Aether Raids.
Lull Atk/Res is Ymir’s preferred B slot skill as it increases her durability and nullifies the foe’s Attack and Resistance buffs. Ruse Skills can also be a good B slot option with a Rally skill.
Sacred Seals that either increase Ymir’s own durability such as Close Def, or seals that help her support her allies such as Distant Guard are her best sacred seal slot options when it comes to AR Defense.

Strengths

Everliving Domain and Everliving Breath

A skill that is essentially a Drive Miracle with stats on top is extremely powerful, and an exclusive weapon that gives herself and allies penalty negation as well as guaranteed follow-up attacks and an absolutely necessary boost to all of her stats is just the cherry on top of the obligatory strong new unit package.

Statline

With a great base Attack of 40 and decent Defenses at base 35 and 34 respectively, Ymir herself is quite tanky on both sides, making her Drive Miracle that much more difficult to get rid of in an Aether Raids context.

Weaknesses

Terrible Speed/Weak to Null Follow-Up

Sword users with Null Follow-Up and/or access to Speed based damage reduction skills can give Ymir a bad time due to her terrible Speed and complete on her weapon’s effects to secure follow-up attacks.
