Eremiya

Weapon: Dazzling Melancholy+ / Dazzling Gravity+ / Dazzling Panic+

Assist: Restore+ / Recover+ / Physic+

Special: Windfire Balm+ / Miracle 

Passive A: Fort. Def/Res / C Duel Infantry / Atk/Spd 2 / Atk/Res 2 

Passive B: Sabotage Atk / Sabotage Spd / Chill Atk/Spd

Passive C: Time’s Pulse / Distant Guard / Flexible

Sacred Seal: Fortress Res / Chill Skill / Savage Blow 

• Eremiya can also take a more supportive role rather than focus primarily on her good offensive statline. Regardless, though, her weapon choice remains rather flexible -- including fantastic choices like Melancholy, Gravity, and her native Panic -- and should be determined based on personal preference and her team. The Dazzling Staff refinement should be taken to safely apply her chosen staff’s effect/ 
• For her healing skill, Restore packs great utility through a decent amount of healing and a debuff cleanse, though Recover may be considered for its much more potent healing properties. Physic is also a potential candidate to provide Eremiya greater range. Windfire Balm+ (or any other Balm Special) and Miracle are once again strong Special choices. 
• Fort. Def/Res grants a powerful raw stat boost to Eremiya to more consistently utilize Sabotage skills (or if unavailable, Ploy skills), but this does detract from her healing slightly through the -2 Attack it inflicts. For Colosseum modes, C Duel Infantry is an excellent A skill to bolster her scoring potential, and on a budget simple stat boosts are once again the way to go. 
• Sabotage skills work well to apply mapwide debuffs on opposing foes, though her below average Resistance does mean that she needs high investment in the stat (such as through using both Fort. Def/Res and the Fortress Res seal) to utilize efficiently. Should one wish to have more consistency but a lesser chance of debilitating multiple foes, Chill skills can be taken instead. 
• Time’s Pulse works well with a Balm Special to constantly make use of their buffing effect, though if unavailable any support C slot skill like her native Distant Guard can be taken. If not using Fortress Res for her designated seal, a Chill skill can be taken, or Savage Blow may be equipped to apply chip damage on foes.

Weapon: Dazzling Melancholy+ / Dazzling Pain+ / Dazzling Gravity+ / Dazzling Panic+

Assist: Restore+ / Recover+ / Physic+

Special: Miracle / Windfire Balm+

Passive A: Atk/Spd Solo / Atk/Spd Push / Atk/Spd Bond

Passive B: Wrathful Staff / Dazzling Staff

Passive C: Savage Blow / Flexible

Sacred Seal: Live to Serve / Savage Blow / Atk/Spd Bond

• Eremiya’s choice of weapon here depends primarily on what her allies require of her or how offensive one wants her to be. The Melancholy, Gravity, and Panic staves are all fantastic utility choices to cripple her foes in combat through their various debuffs, while the Pain staff is a fantastic choice to stack chip damage on opponents to greatly reduce their health. The refinement on her weapon should depend on what B slot one has available -- if Wrathful Staff is available as a B slot, take a Dazzling refine and vice versa. 
• Miracle is a good Special option to provide Eremiya some defensive options and allow her to safely take a lethal enemy hit if the situation calls for it. Alternatively, Windfire Balm or any other Balm Special may be taken for a more supportive focus and provide teamwide buffs to her allies. 
• Any offensive A slot (that a healer can inherit) will work perfectly fine here, with Eremiya’s best options being Atk/Spd Solo and Atk/Spd Push. Although Atk/Spd Bond can be a bit unwieldy to utilize in the Player Phase, it remains a decent option nonetheless and it should be noted that Atk/Spd Bond 4 does come with the benefit of allowing Eremiya to bypass offensive stat debuffs. On a budget, Atk/Spd 2 or any simple stat boost skill can be taken. 
• Savage Blow is a strong C slot choice to apply chip damage on opposing foes, pairing particularly well with the Pain staff and can be taken even further with Savage Blow in the seal slot. Other than that, the Live to Serve seal is excellent to mitigate any damage Eremiya may take or Atk/Spd Bond may be taken to enhance her offenses.
