Welcome back to another episode of Setsuna destroys grand hero battle! We've got a bout with some rock hard armors so Setsuna is coming in with some poison. Perhaps Bride Cordelia was a victim of that poison herself!
In all seriousness, for a physical damage dealers like archers, the real enemy of this bout are the armor reinforcements.
With the help of poison strike and luna, Setsuna is able to pierce that defense of the armors. Every other enemy in this GHB can be orkoed by Setsuna and you don't even need that much attack to do that. So the focus of this GHB for us is the armors that we need to kill in 3 rounds of combat. To be able to achieve that feat, along with poison strike and luna, your brave bow archer needs to hit 46 attack after buffs and skills(and obviously be fast enough to quad).
As for your speed, your archer does need to be able to quad the horse units, so they will need 32 speed after buffs and skills. My setsuna has 32 speed naturally and she reached 48 attack after a hone attack 3 buff.
I bring the standard 3 olivias. The important thing to note is that two of them need to tank a hit from the Green armor unit, but that is simple to deal with as even a 3* level 40 olivia can do that. You can try to kill the green armor first if you have to use a blue dance but the positioning would be all different. The important thing to note is that if you have one olivia with slightly defense than another like I do, then the lower defense Olivia must be positioned in the same spot as my Olivia with 30 HP and 23 Def(the weaker one). This affects who the Green armor will attack first so we will control where he goes a little.
So in summary if you have a brave bow archer that can reach 46 attack and 32 speed after buffs and skills, and has poison strike 3, you can follow this strategy.
