After she reach 30% hp, she will cast Power-Up, Agi-Up, Quicken and EQ. I use +9 2*AK Gungnir EA10 to deal with her Agi-Up. The catch is after she reach 30% hp, whether you can kill her during Inspiration time. Because after inspiration your dps will be very low, and you gonna waste tons of YGGs. I choose to disengage and rebuff once she start to cast EQ
I actually hesitated a bit if I should upload this one, because that one fly wing disengage looks stupid. However not really sure if I can tanking her while casting inspiration and re-buff. The biggest challenge is that I have to switch to Imperial Guard for more Shield Spell ATK buff and to rebuff myself, and switch back to GTB Valk again. All these has to be done between the gap of her EQ, which is like 20 seconds. If Shield Spell mess up with me that I can't get the ATK buff then I am dead. So I consider this a safer way to do.
If anyone want to try, theoretically the order should be Switch to Phen Accessory -> Switch Weapon (if necessary) -> Wait for her to EQ -> Switch Shield -> Wait for her to Dispell -> Inspiration -> Piety (Inspiration cancels piety, and her holy attack damage is insane) -> Other Self Buffs (Defensive Buffs first) -> Switch back to GTB shield -> Switch back to your original accessory. This process should be done within like 20-30 seconds (Whatever her Cool Down on EQ and Dispell are). On the same time spam YGGs.
Thank you and hope some one can make a video of RG solo Valk w/o death or disengage.
