i gave her Special Spiral 3 but im not sure about her A skill, C skill and Seal. im thinking Death Blow 3 for A and Threaten res 3 for C but im not sure.
(never mind Glimmer, im changing that to Blazing Light)
do you have Hana/Sothe?
LND is her best friend because her best IV is Atk/Spd (which it will help) and her def is crap anyway (which it lowers).
Threaten Res was something i thought about, but theoretically. it does nothing for her. unless she's danced out of the way. Savage Blow COULD work if using her on anything higher than infernal and helping with chip damage (leaving her SS slot open to something else).
I recommend against burning feathers like that. If anything, use L&D2 for now until you pull Sothe, unless you're merging Sothe (in which case I would probably stick with L&D2 for a long time unless I randomly pulled something else to fodder for L&D like a second Minerva or something like that)
With special spiral on Ophelia you need to use an AoE skill, that's the best special for her as she is able to have it turn 1 and keep having it all the time.
For that build the best A slot is Life & Death as it will increase the dmg of the AoE special while Death blow does not.
C slot is flexible, anything can work, obviously the best choice is Odd atk wave (i don't know if we have the even version)
The best seal is Hardy bearing to avoid getting killed by Vantage
Maybe Life and Death 3 in A, her def and res aren't the best and her spd is at a point where it likely she'll get double. I did this for my +atk -def Delthea and she worked wonders. For C you put anything you put anything depending on the team and for a seal quicken pulse just to get the Blazing Light proc
