okay serious question time
Are Gabriel/Alrescha/Alrescha/Andromeda good as subs for Neptunedora? Because if it's legit enough...
Well. I have Orochi, Isis, I&I and Sachi Bros if double Alrescha is not preferable.
My NepDra team is not great, but here's what I use:
NepDra/Reine/Gabriel/Snow White/Alrescha/NepDra (although recently I've been pairing him with Ryune a lot with some success)
As I've said before, I think my team has two major weaknesses: Low HP and few skillboosts. The team you're proposing has slightly better HP, which is good, but even fewer skillboosts, which I would say is bad. I'm definitely a fan of Alrescha on Neptune Dragon, her HP isn't horrible, she makes him lockproof, and extra haste is great, but I wouldn't use two because it slows down an already-slow team even more. Once you do get your skills up you'll basically be set for a while because of all the haste, but you don't have any fast skills which is very bad.
Here's my ill-informed take on all of the subs you mentioned:
Gabriel: Very solid, especially if you have a lot of physicals already and need RCV. Even better if you have a heartbreaker. Bad HP is super sketchy though.
Alrescha: One is great, especially if she puts you exactly at five lock resists. Two is probably overkill outside of certain dungeons.
Andromeda: Great. No real downsides that I can see.
Orochi: HP and skillboosts are both great, lack of God typing is unfortunate and I'm hesitant to have any more non-orbchange actives. Probably becomes an amazing choice whenever you pair NepDra with an orbchanging friend lead, although odds are that will hurt your RCV even more. In my case I still have more than enough, but my team is heaven on healers.
Isis: I wouldn't use her over Snow White, but she does have better awakenings and stats so there's certainly a reason to. Definitely better than Snow White if you don't pack a heartbreaker, but you should probably have a heartbreaker. Her shield could be relevant depending on your team's final HP, but it's too small for my team to care about.
I&I: HP good, active semi-pointless. More haste is great, and in theory it lets you burst while conserving orbs, but it still seems like overkill to me.
Sachi Bros: Doesn't seem especially great at anything NepDra wants to have, but could be good if you have a green->blue orbchanger.
To be honest Neptune Dragon seems like he needs a heavy whale box to really work. He has too many flaws that can only be easily solved by stacking REM chases. Or maybe I should be pairing him with something and I'm just playing him bad. But as it stands I can't reaaally recommend him. Too flawed and needy.
Edit:
Commander, I did some searching, found this:
>I pretty much have it down to a 100% clear rate at this point with Gabriel/Reine/Snow White/Alrescha/Sun Quan/Ryune.
I also found this in your post history if it helps out any
Thank you very much, that helped a ton. Who knows how long it would have taken me to figure that out again. I died a number of times earlier, but the first time I busted out Alrescha it was a breeze to clear.
