By CAFC: Only leaders and a defence-breaking golem or similar actually required, others use high attack/hp to cover all colours. Stall on floors 1 to 7 as much as possible to get defence-breaker up. Floors 8 and 9, two sets of four combos should KO. Floor 10, use defence-breaker then any other skills and four combo for KO.
By taiko: Tank everything to death.
4/2/2. Snow Globe for HP and RCV. Batman for HP and ATK.
You can replace Lilith with Neptune. Kurone can be any strong heartmaker, preferably with some autoheal awakening. Just make sure you stay above 38946 health. Zombie match orbs away and cycle through actives.
By kfcfighter: For floor 1-7 match orbs and stall for hades. You can match 8 orbs for each floor and it should one shot all the monsters. On floor 8 use only CDKs skill to help clear tyrannos. On floor 9 use every skill you have besides lilith and hades to help you clear leviathan. On floor 10 use hades then lilith and keep matching til he die
By ravenspire: Death or glory at its finest: take hits from mobs sparingly, unless you've something to heal you back up (e.g. Dark Venus/Ceres, PEKKA). DJ's mainly there to generate heals for Duke to work with. You're unlikely to stall for Satan with this setup, but if you do, have fun one-shotting the boss. And remember: BRING YOUR BIG GUNS.
By ravenspire: Same deal as the ADK build mentioned earlier; a fully-Awakened G-Sonia should save you some time in charging up Droidragon (discounting other subs with S+). Stall for as long as possible (use Pyros/Dub-Sapphlits where available), then curbstomp your way to victory. ADK buddies work too if you don't have G-Sonias to pair up with.
By ravenspire: Another Big Blue team, this time a bit more assault-oriented. Sieg and Hermes' multiplier should provide you with enough firepower to bulldoze through most mobs, so your focus should be stalling (ESPECIALLY for Droidragon) in preparation for the last two waves to one-shot the bosses. Swap Orochi for Hrungnir if need be.
By Aqua: Sweep first 7 floors, use Echi cool down if gets dicey, charge on skill on Tyrannos. On Levi, pop Echi, then use Gigas > Persephone > Kamui skills for a pseudo Haku active, use Haku active next turn, then finish it before time run out. MS last boss.
By Dave@r/,PG: Very safe build; Megalo was max-skilled. A Leviathan is recoverable with some skill/luck, but with Megalo, I&I and Hermes a burst attack should take him nearly all the way down. Orochi for emergencies, Droidragon for Crystal Aurora Boss.
By Alex: Pretty easy. Use Batman + Luci for 4x hp, pad with RK to get HP up over 40k after multipliers so you can survive leviathan. Max skill siren makes this trivial - you can use Guard Stance - Water once for every attack he makes. Save morningstar for the final boss and just grind through everything else. Never had to activate RK
By FormX: Naturally, just ADK it. Just include Top/shiva and a water dragon, charge when possible and it will be easy.
By derrick: Basically, it's a zombie like team. As soon as you play with the team careful enough in the first 7 levels. You are done for this sub-dungeon. Odin simply reduces all the attacks and archangel recovers the HP immediately. For the last level, neptune's skill kills the dragon within 6 turns.
By Lin失憶: Slow but safe build. Charge up everything excep hino on 1-2, Use odin if can't survive floor 1-7 and recharge. Keep full blood to survive lv 8,9, use Echidna if need to(didn't need to use it though). Use droidragon then hino or ordin to kill the boss. Can replace hino with any monster with a bomb skill.
By b: Super quick clear. Combo through first 7 stages, use Gabriel, CAD and Isis to get out of sticky situations. Stage 8 you can use Isis but that's it. Stage 9 use Lucifer then 3+ combo to dead (try not to use Orochi). Stage 10 pop Orochi if CAD is down, or no 3+ combo. Use Droidragon (or Shiva) then blast.
By JD@PG: Double Cu Chulainn will make this dungeon quicker, 9X the damaged for balanced monsters. For facing Crystal Aurora Dragon, save up until Kano's skill is up, use her skill and then use Cu Chulainn's skill to nuke the final boss.
By abc: Rd1-7: charge skills; Rd8: use Kamui to change green orbs to blue; Rd9: clear orbs leaving some hearts and greens before popping king woodsie and Cu Chulainn skills; Rd10: Reduce defence and use Cu Chulainn skill to kill
By James: Artemis for HP and RCV boost. Pop Indra right before Leviathan attacks on FLR 9. Neptune takes care of CAD in ~4 turns.
By James: Use balance of dark/wood to combo minimally so as to maintain a good supply of offensive orbs. Only one CDK and ADK needed for dungeon to be cleared consistently. Clear Tyrannos with regular combos and store up fire/wood gems as needed on Leviathan. Use gem changers on Crystal Aurora and clear with a wood-based combo.
By Syd: Wildcard should be any good grass monster. Mostly grass team will get through early stages easily. Siren for more RCV and multiple Pyro Demons. Golem half dmg skill + Neptune's half dmg from water allows you to take one hit from Leviathan if you have over 9.8k HP. Kill before Leviathan attacks again. Neptune poison kills boss.
By AdarSA: Pretty easy clear if you have an Odin, Neptune or Shiva leader and a friend with one of the three. You need to survive stage 9 (a max skill siren makes this easy) but can then insta-drop the boss with Odin + one of the others. Make sure to have at least one nuke always up in the trash stages.
