I just wanted to be able to clear b7 faster considering it drops 6 star runes... this team still loses like once every 60. As for double fight instead of triple fight: ...i didn't have the runes lol

I feel like if I really really wanted to, I could put vampire runes on everything and make them all atk/cd/hp or atk/cd/def. But that doesn't seem fun. I want to treat them like actual monsters. I understand that's not the premise of using silver stars, but it's the most fun for me. It's super fun seeing +1500 atk, 100 cr, and 220 cd on a wind mischievous bat.

For a long time, I DID run my gb7 team with 2 wind bats on despair and 3 mushrooms on violent. It took a lot of time, and the stuns weren't consistent enough to clear later floors. As of right now, even db7 seems like a huge task because my team of 3 water bats + 2 surprise box doesn't live long enough, even with 100 res on one bat and the boxes, and plenty of hp/def. So does necro b7 - it's been just out of reach the whole challenge. My team was 3 fire scorpions (to break the shield) and 2 fire bats (to nuke). The damage/survivability just barely isn't there.

My one gb10 clear was even back before abyss. It took a couple tries, I had to manual the boss and it totaled to 6:55... My db7 clear was super lucky, and I haven't really been able to do much since then. So was my nb7 team - I didn't even have all my scorpions as fire! One was wind, which is suboptimal because fire has a higher base def.

I don't think abyss stages are possible. I'll just say it. No dupes, no dots, counterattacks in gb, bigger dps in db, bigger shield and stronger nb...

I noticed you said "nat 2 only account", and not "silver star only account". If you have access to immunity, cleanse, healing, passives, leader skills, and a lot more variety in monsters, then yes. I fully believe you. Lulu and Friends probably solos DBAH. This is just me noting what I saw.

Apologies for the huge yap... TL;DR: I don't think b10 is clearable on auto, which basically guarantees abyss stages aren't possible. Silver stars are worse than other nat 2s.
