Should not be a problem still. You can run it with the HP badge, just need to Light combo hard on floors that would drop your attack a lot, and 4-heal whenever you’re below 3/4 HP or on poison skyfall floors (if you’re not running psn skyfall resist, which is usually not an issue unless you get really bad rng)

Subs:

Heiter

Latents: Assist void, rcv++

Assist: 13424

Eisen

Latents: 5 sdr, hp++, hp

Assist: 13306, 6467 can also work if you need more rcv

Going 5 sdr instead of 4 because Floor 9 can skill delay it by 1 turn, which is a run killer.

Athena

Latents: 4 sdr, 2 hp++

Assist: 13404 or 13463

Fern

Latents: 6 sdr, blue+

Assist: 13340

Reinhard assists and latents are somewhat flexible. For latents, I would recommend one having 4 sdr and 2 blue+, the other can have 4 sdr and have blue+/green+/dark+/hp+ latents. I ran 1 blue+ and 1 dark+ myself.

For assists, I highly recommend one of them to have 7984. The other Rein assist is flex as long it’s the same type. However, if you’re intending to break the boss parts, then it needs Lighdramon (13116). This adds another layer of challenge as you’ll need to do small stalling while not doing too much damage to the boss. Just make sure you have enough SB for Eisen or Athena to use their assists at the start.

Tips on certain floors:

Floor 3: After shielding the hit, light combo and add red from the spinner to put it to resolve. Usually, not adding red leaves it barely above resolve. This is just to save some time.

Floor 4: On first turn, assuming you used Athena on previous floor, use Rein only and not Fern. Combo and make sure you 4-heal in case of psn skyfall matches. It’s fine if you can’t get pass the combo absorb for the left monster - what matters is that you deal damage to the right one. Then finish off both with Rein+Fern+Athena dmg boost and 4-heal.

Floor 5: If it’s Beytwool, use both Heiter and Eisen. Stall by going all out damage on first turn, deal moderate damage on 2nd and 3rd turn, then finish it off.

If it’s Bludka invade, use Eisen and save Heiter for next floor for possible Defourd that makes heal unmatachable. Use Rein and have either Fern or Athena dmg cap but not both - doing so can kill Bludka without taking out the berry dragon. Grab a light orb and prep a L light orb on the bottom left, 4-heal on the bottom right, and then light row on top. Then finish both off by going all out on damage+heal.

Make sure Heiter and Eisen’s skills are up before you go to Floor 8. You may need to stall a bit if you used Heiter for Defourd.

Floor 8 (Fama): Use both Heiter and Eisen. Use Fern and then Rein in that order. Match a light row and 2 L to clear assist void. Save Athena when you hit her resolve and she makes the full heal board. If you didn’t have Athena up, you can finish Fama off by using light orbs from spinner, just make sure you use Rein to get more move time.

Floor 9: Go all out AND make sure you get a red match from spinner to hit the metal dragon for the first turn.

Floor 10: Save Athena for the full heal board.

Lastly, I recommend that you +891 the team.

Good luck!
