Thanks for answers. I have a few questions about them.

Make sure you farm Vine, as that'll greatly improve your damage
Vine have a 10% DEf summon debuff, is this better than 20% hp/atq from Disaster Wind eidolon? Because i have to wait 8 turns to use Vine debuff.

You write:
Each additional percentage point provides more benefit than the last. Reducing DEF from -40% to -50% increases damages by 20%, nearly double the benefit of 0% to 10%.

But in this case, i would lost 20% hp/atq from Disaster Wind eidolon. I know damage and atq don not the same, but i wanna understand if Vine is always better than Disaster Wind eidolon. I think, Vine could serve me situationally, ie. Acc Quest. Is it right?


By other hand, i have thinking which hime use in the main team and an strategy. Then, i had some questions.

Main team 1 - Endurance
Joan- Endurance / Extra ability: sniper shot (Def/Atq debuff B class)
Cu Chulainn - Damage
Gaia - endurance /(soft heal awakening)
Oberon - Def/Atq debuff A class
Caspiel* - Atq debuff ? class

35% Def debuff
50% Atq debuff (cap)
20% Def buff
2x 40% DMG reduction

Main team 2- Endurance
Joan- Endurance / Extra ability: black propaganda
Cu Chulainn - Damage
Gaia - endurance /(soft heal awakening)
Oberon & Cybele - Def/Atq debuff A & B class

35% Def debuff
2x 40% DMG reduction

Main team 3 - Balanced
Mordred - Utility / Extra ability: sniper shot (Def/Atq debuff B class)
Cu Chulainn - Damage
Gaia - endurance /(soft heal awakening)
Oberon - Def/Atq debuff A class
Guan Yu - Atq buff

35% Def/Atq debuff
1x 40% DMG reduction
More damage

Questions:
  • Should i use Caspiel in this build or better use other hime?
  • Is it too much endurance in the build 1?
  • what class of debuff does caspiel have? no class?
  • what do you think about them? some tip o recommendation?
