Angie's using a prophetic candle as you suggested. She was using rod of amyrillis before, but I think she can do without it as long as I upgrade her healing spells with more molas.
Right now in W11 she slowly falls behind on healing herself and survives just long enough to hit shield phase. Then she gets a chance to heal back up. I only just barely crack the shield each time with Arky's help.
I'm using Taranor Guard for defense breaking because it takes less maintenance than Karin's break, which I assume makes him more auto-friendly later on. He's at 88% effectiveness and seemingly still only lands a successful break three or four times per run lol.
I'm also using Alexa as the dps for now, because I heard she's easier to gear for W11 than Karin, which it turns out she is, since I just threw on the tier 71 abyss gear, upgraded them to +6 or so, and sent her off. I'll probably go back to Karin later since I want to 6* her, but that also means I'll need to regear TG since Karin is faster.
Yeah, that's basically how I started out until I could get Angie a little more beefy on the HP side, then it becomes easier to auto. Even if Auto if Dizzy misses with her S3 she might get wiped by the time shield phase rolls around but I can survive long enough without her in the next damage phase to finish Wyvern off.
I use TG as well, he's worth the Mola investment in S1 to get the Def Break proc chance up (three skill-ups). Don't forget to turn off his Skill Use when you go to Auto 11, you only want him using S1. Also remember when he dual attacks he provides a CR boost to the team so Unity Gear is also an option for him. If you time Dizzy right to use her S3 in the shield phase you might actually be able to withstand taking the blow (depending on your teams gear) and save Arky for more burn down. Needs to be fast to get it back up though, mines at like 222 speed.
The other option for Angie is Water's Origin, which takes some tweaking of her HP. Basically she'll revive a little and CR boost when she gets hit if each hit is 20% more than her HP. That might not be the case when Dizzy's S3 is debuffing Wyvern but when not debuffed it may provide some more sustain.
One thing that made my clears faster/more consistent was swapping Luna's hodgepodge set of gear out for a Rage set. So keep an eye out for that once you start raiding. Since TG/Dizzy are constantly applying debuffs she absolutely shreds and Alexa could similarly benefit.
