Speaking of Edgar, is it worth keeping dupes of him or Carrie for whatever that auto bowgun combo insanity was about someone posted? Or not worth the effort?
Here :
Edgar and Carrie's auto-bowgun confirmed OPIt's combo and elemental chain that are.

You need multiple weapons of the same element, someone with armor erasor like 6* WoL (DEF/SPR -45%) and a strong damage dealer.
Firion get crazy passives at 6* like : "+30% ATK when equipped with Axe & +30% ATK when equipped with Hammer & +30% ATK when equipped with Lance & +30% ATK when equipped with Knuckle" combine that with his awesome innate Killer abilities and the fact he can equip every weapons.
So we gotta wait for armor erasor (full break might work) and if you have the units you can always try it.
