Bluhh. Getting Verdandi kinda has me spoiled for choice.
Awoken Bastet potential subs now include:
A. Parvati (excellent active/awakenings/stats, very hard sell to swap her out)
G/R Liu Bei (triple TPA chainsaw murderer, blow-your-house-down active)
Perseus (Hero active is too good, but maybe a little less synergy on teams with multiple G/R?)
A. Meimei (excellent active/awakening/stats, she's just... not in PAD US yet)
Michael (would need to skill/level him up, but holy shit his active works well with Meimei's; awakenings kinda suck though)
GZL (Worth using if running Liu Bei/Meimei/Michael, maybe? Otherwise...)
Green Wee Jas (a lot of stuff doesn't resist delay these days, double Extend Time is great, but not really worth using unless I can skill him up)
Verdandi (It's Verdandi)
Few others like Sasuke/Artemis/Kano etc, but not really worth considering.
Prior to landing Verdandi I was going to go with Bastet/Liu Bei/Parvati/Meimei/Perseus/Bastet, which seems fantastic on paper, but Verdandi's just so good... hrlhfglh.
Sasuke's definitely worth considering since he's a 5cd orb changer. I'd say swap Parvati or Sasuke depending on the dungeon, only one 5cd orb changer should be enough anyways.
GZL and Wee Jas are kinda too slow, you don't need the enhance from GZL for almost every case (if you do need enhance, Shotel is infinitely better but you gotta pull her first welp), Wee Jas can be situationally good though, just keep that in mind.
If you use Meimei then do Michael, if you use Verdandi then use Perseus seems to be the more logical choice, definitely go Perseus if you need SBR for something.
Liu Bei is a given.
In general, I'd say use Bastet/ (Parvati/Sasuke), (Meimei/Verdandi), (Perseus,Michael), Liu Bei / Bastet
Do you have any shield choices like kushi or susanoo (or even Indra)? You'd definitely need something like that for some dungeons.
I don't believe there's a template party for bastet and gungho's newer dungeon designs really force you to think outside the box sometimes, so just keep your options in mind and change accordingly.
Are you aware trance wrote a comprehensive guide on A. Bastet on reddit?
