pretty sure you need to do this on the right maestro otherwise you will get hit (you can use the foreground candle to lineup like shown in the videos) you just have to do nail > clawline > nail > pogo > spear > dash > upslash between the nail and pogo after clawline you have to move back a tiny bit or it wont work
(getting hit or not is kinda rng so idk if you would go for this is runs but ill still put it here :3)
If you knock the Maestro away from its minions fast enough, it wastes its attack (trying to recall its minions). If you're low on silk, you can use this to farm enough silk to double spear the other maestro, or you can just silkspear the maestro against the wall for a fairly quick kill.
I'm not sure if this is consistent. If you do the first two hits really fast, I think the maestro can spawn its minions closer to the wall which allows the maestro to attack, so you should be ready to react to an attack regardless.
I like this strat for dealing with the two maestros. Right side for the first guy seems more consistent/safer to me than left side, as long as you don't get the spinning attack the first guy should be consistent damageless with this strat. I think you lose time on the spinning attack, but save time on the other attack with this
Then the second guy i am assuming you want to do one spear, note here that you need to bait the guy to attack left after the first two hits. None of what is in the clip is particularly consistent, but i think it's more consistent than other strats and good to go for. You do need to improvize stuff a bit quite often. For the spinning attack i think you should wait it out and you can go for a nail dash nail at the end of it, although that can get you hit
I think if you wanna heal it's best to heal at the clapper and get silk for it there, if you try to nail only the second guy it will probably not be much faster than healing at the clapper if faster at all, and you will just get hit more
