By TehDemoNic: Leader- Any 50% water resistance. Auto heal is amazing. It helps out a lot when you have to fight 5 devils Maxed out Grodin helps alot. I had like 4k auto heal. Delays helps alot when fighting the devils. Having high rcv with auto heal kept me alive. Orb changer to heart helps alot too.
By ralphh: I took nebradisk for the boss level as insurance, but wasn't needed. Other builds show dual Zeal leaders and that would have defeated the boss in 8 turns. If you don't have him, this is a good way to usea multiplier for most of the levels, and if you aren't able to clear the boss in time, nebradisk is a great blocker.
By Fix: i guess the 4th and 5th card could be any dragon (tho the 2nd apocalypse was good for the heal.. possibly not necessary if i had used echidna instead... she was mainly there for an 'oh crap' button) dragon shogun and apocalypse leads gave the damage needed to one shot most floors.
By milkyway: Bodin, samuria dragon and Atremis fully awoken. Avalon drake one awakening. ? was Poporing #184. Use orb changer as needed. Save Drake and Zhuge Liang for boss. Bodin samurai actives whenever for emergencies.
By ravenspire: Not really much to write home about here: stall as much as you can, then wipe the floor with everything you see. Tailor Green Dragon wildcards to taste. You should have at least ADKZ max-skilled to keep that ammo flowing, everything else is optional. Now go wild, and happy hunting folks! ;)
By Lairecay: Kinda safe build. First 9 rounds are kinda shaky. Heal every turn. On boss, use Lucifer on 1st turn with Vert and Brachys. With a bit of skill, you can kill the boss.
By ELCT: Just fall well below 80% and stat murkin. Try to fall to around 40% just to be safe. You will one shot almost everyone. Once you get to final monster just use flamie.
By Eggs@PG: Any subs will do for the last 2spots, I wan it with Dub-emelits. Use Graviton's active skill to take out floors of devils if in a tight spot, or to weaken the 2 sirens on the 2nd floor. I recommend using KOR's active to half incoming damage from the sirens. Use Bastet's active on the sirens to finish quick. Overall easy to build
By KTastrophe: Very quick, hard-hitting build. Avg. Lvl was ~45. Combo of x3 every round should wipe out any number of demons, weaker attacks can follow to kill knights; nothing should be able to put a scratch on you. Change Fr to Gr, Lt to Dk at bosses, and it's a snap. Never had to change Lt to Hl, and def break is just icing on the cake.
By Peter@PG: If you don't get 3 orbs of DK WD and WT when you start the dungeon, you are screwed. other than that, If you activate Haku's skill, each round takes one turn. Once you get Dance of the tigers roar for all three Haku's you are set. Generally you can 1 or 2 shot Nifilheim
By codenamez: With around 8 combo should clear each round in one. Charge up skill in round 5 and then use all skill against boss all at once. Got boss each time a ran the dungeon during 2x drop rate
By Iggy: High HP team, Neptune gives half damage reduction and gets the 2x ATK from Batman for both its water and dark att. Use skills as necessary, charge on Rd. 5 Plesios. Make sure at least one KOR skill is charged and HP is full When Nilfheim attacks, brings his hit down to ~18000
By Eric: Try to get Keepers of Rainbows skill built up before bosses, its good to have if you dont get much luck at eliminating orbs.
Had no problems at all, simply bashed through with combos (mostly luck, since I'm not that good with combos).
By ben: Very safe build, just make sure skills are up at the end of every turn. Use odin to kill one devil and vrita on anouther, then finish that one off. Take your time on the rest. Piece of cake. All around level 50 odin is 70.
By Mesamashi: Preferably max skill on siren and 1~2 valk. Bore through everything and use siren and valk on boss. Pop a echidna when needed, lilith and alraune are there for atk.
| || ||10|
david: Similar to my build, however i used king shynee instead of lilith because 3x atk for healer one turn, and L Meta instead of valk. Good healer spike team would be with sun quan, then no shynee required.
By Smooth: This is a very defensive build. Both leaders must halve the damage from water monsters. Stall in rounds 5 and 9 to fully charge skills. All skills are needed in round 10, and once used should reduce Nifhelms damage to under half. Finish it with 5+ combos in about 5 turns. Neptunes poison is a must.
By kivanc: Leaders: any 50% resist
Megalodran: good for HP orbs
Rippers: Good for normal floors
Lagavulin's can be replaced with a ripper.
1: Kill 1, charge
2-4 & 6-8: Use Lagavulin, ripper, and KoRs
9: Kill 1 quick, can use KoR. Stall 2nd to charge 1 KoR
10: Use KoRs to get 1/8 damage. Takes a while to collect the gold egg
By dustmannPF: Genbu, Artemis, ADK provide extra burst + orb changing. Not necessary if skilled at combos. Parvati is nice for hearts when/if you get orb trolled. Freyja burst on the boss, easy in 8 turns. All members ~ lvl 50 with a max level Artemis friend.
By Enleed @PF: Charge and play normally until boss. Haku not necessary at all, just used her for burst damage and the fire in it is great with siren if you end up heartless. On the boss, gravity Lucifer with a few attacks and win.
By JD@PG: Running double Cu Chulainn will make this dungeon go easier. Keep attacking the monsters. Use Cu Chulainn and the Mystic Knights skill to defeat the final boss. You should get the egg after it.
By OmniLiquid: Use one luci on 5, but make sure hearts are on the board first. Just keep hp up and make sure Luci skills are up before clearing 9. Use Lilith to make imps everything die slightly faster, keeper to defend against large groups, cdk for an occasional damage boost. Should be easy (but slow) to 0 stone with levels around 50.
By KingAuzzie: All subs can be whatever you like as long as health is around 10k. You have the health and recovery to take on everything before the boss, and 8 turns to beat the living daylights out of him. Extremely easy.
By Unum Draco: Floors 1 - 9 Charge skills. Floor 10 Gravity, Gravity, Nuke and Win. Easy, Safe and Fast.
By Knight Fox: Mono-green build just a matter of leveling the board. My Artie is maxed, as is Alraune both and Laga max awoken. You can take a bit of punishment with this team but getting it back could be an issue. 8 turns... heh the boss is lucky to survive to turn 4. Save Laga for 5 devil floors and ADKZ for Pleisos and the Sirens.
By BRAAAT: Even if you don't ultimate evolve ADK this build should work, given that your monsters are decently leveled (30-50). Wild Cards can be any dragons. Echidna replaceable with Siren, given that you have the levels in your other monsters. Ultimate Evo Indra or Ultimate Evo Chaos Dragon Knight also work as leaders.
By noxiate: This was my team, A simple ADK team with rippers. You can replace Graviton Earth Dragon with any other wood dragon and slot 3/4/5 can be replaced with any other dragon.
By Manny: The key to this build is 3+ combos the two dragon knights give you a combined 6x atk. It reall mly took me like 10-15 mins, I just put 20 to be safe. It was a very easy run through. Empress is just a safety sub in case you have no health orbs and need a few extra turns to get your HP back up.
By Lyrtes: Standard dual lucifer team, use vamps skill when you are feeling safe and jokers skill when you need hearts. CDD is used to speed up normal floors, can be replaced with a RK if you prefer a safer build. Make sure both lucifers are charged for the boss, don't use them beforehand.
By Gush3rs: You can basically one shot everything on every stage. Use ADK's ability on the sirens and boss stage to get a OHKO. NOTE: the subs can be any dragons, except fire obviously.
By Poo Poo: SOD lvls were around 70 and 35. Made sure to kill aqua knight first all the time and stall. Whenever there are four enemies attacking in one or two turns, I popped my keeper skill. On stage 9, use one MS and stall for the skill to come back up while slowly killing the siren! Then nuke and finish! Don't need that much HP imo.
By Gleam: Actually used evo'd CDK & ADK for 9x balance, I just sniped with black, cleared with green and did an orb switch and a combo to clear the boss.
By runest: Min defensive build. Can sub Wood Mech with anything with Defensive Stance (like a Keeper). Can sub Neptune w/ half water damage monster. Charge up skills and use if in danger. Against Ice dragon: Poison w/ Neptune, use Defense Stance @ ln 3. Use Echidna right after he attacks, then right when she charges (~ln 4). Repeat.
By dqi@PG: Maximum skilled DVP and CDK are suggested. Use orb change skills to swipe floors have 5 devils. Make sure you get Lucifer's skill ready before the boss floor. After using the morning star, you'll only need 2 or 3 rounds to finish it.
By Emm@PF: Luxury build if you have Holy Thunderdragon Indra. You don't really need 23k hp that's just what I had. This is a nice tanky/ripper build that is pretty safe; you can take a couple hits without dying. ADK + Indra damage bonus to should be able to rip thru all the lvls and kill the boss in 2-4 turns. Save your skills. Done!
By Daed: Grass team on a water dungeon. Easy peasy. The monsters in this team is fairly easy to obtain. 1 green + 2 or 3 combo can wipe pretty much any floor. If you managed to get stuck, nuke the devils with the dragons. Store skills on floor 5 and 9. On boss, 8 turns is more than enough to finish him off.
By さとし: Should be safe as long as you heal to max hp every turn siren is max skill to be safer. Use rippers when there are 3 or more devils, or when needed. Hp will depend on your monsters and the Odin but I had over 11,000 hp. Oh and don't forget to charge skills on 1st and 5th round
By bk @PF: Any 4x(attack)x2x2 mono build should work (even red). Levels in the 30-40s. Just save the big orb changers for boss. Rest of the floors are pretty harmless.
By Enkidu: Use rainbow skill when lacking heal orbs, one combo of heal orbs heals around 5k+, CDD for quick wipe out of big groups, save Hades and Lucifer's skill for Niflhelm (and HQ persephone if you want since you'll need to combo a few to finish him off. 5th member can be another CDD, keeper or something of choice.
By warReno@PG: Simple ADK team. Match green orbs between turns for optimum efficiency. Use ADK skill if in danger. Try to get at least 4/5+ combo. Unleash all skills against boss. Should take 1-3 turns.
By Sokunh@PGF: It works best with heavy metal dragon just as a multiplier but can easily be substituted with double Ancient dragon knight, make sure to heal enough and take out ice plesious quickly. Make sure to charge Freyja's and at least one dragon knight's skill at the boss and wait for the best time to use them.
By Sir Otto: all the members in this team are at the max level, none of the dungeon monsters had a chance to do any real damage to this team, even when i reached the ice dragon i was able to finish him in 4 moves. i did not use any stones.

Tibbles: This would be a very excellent build provided that the Mech dragon is actually available for the English version and you're over the rank of 350.
By Fluffle@PF: Store for Ogre's skill at stage 1 and use on floors with 5x devils, at any other spawn simply throw out menace and grind. Ogre is not absolutely necessary and can be unevolved if any color resist dragon or all target nuke is used in the last spot. Naga can be somewhat replaced if there's enough cost for another Rainbow Keeper.
By James: Odin team. ??? can be wood or defensive (e.g. Keeper of Rainbow, Echidna). Charge skills in round 1 vs. one enemy. Clear 2-4 with dragon abilities (vs. many devils) or other abilities/combos. Recharge on 5. Repeat for 6-8, recharging when possible. Focus on one Siren. Full HP survives Niflheim. Amaterasu Ohkami improves Siren.
| || ||00|
Manh: Didn't work for me D:
By James: Basic team for Master. Keeper and ??? sub for good wood or RCV (e.g. Echidna, Siren). Orochi improves Ogre. Charge skills in round 1, store wood, advance. Use dragons for two floors with many devils and multi-target combo or delay for third. Recharge on 5 and repeat for 6-8. HP >70% (50% with Orochi) to survive Niflheim.
