Below are sample teams that have successfully conquered this dungeon. You are welcome to share your own teams and tips here. (Please reference Sample Team Guidelines for suggestions on contributing.)
3 Heras because I'm lazy and solve problems with just actives. Start charging skills at 1F, and just KO 3/6/10F bosses with Hera and Lucifer. Same deal with invades. Siren is max skilled so I don't get starved on heal orbs. 0-stone easy clear~
Just grind through 3/6/9F, use Baddie and Vampire as needed. On 10F use double gravities and Lucifer, then use Baddie and Vampire to finish the boss off. The other floors need no explanation. Easy 0-stone clear
Non-IAP grind team with Noel Rouge, avg. level ~60, Gigas and Echidna max skilled. Such a pain to grind with mono-fire because 6F is too easy with hitting for only 1 HP. Use skills when ready, otherwise heal =.= Take your time at boss, just note that once she starts to multi-hit, heal every turn while keeping 2~3 heal orbs on the board (4~5 combo recommended), (Gigas is useless here now, just stat stick) fight on and you'll win out. It took me six hours, completely exhausted after I came out. P.S.: Can switch out for , swap for anything with similar stats, swap for or , friend swap for for more efficiency and safety!
HP team, faceroll clear
Non-IAP team, average lvl 30 not counting , charge skills and you'll clear it.
Average level 60, safe as heaven, just match as much as you can, you won't die even if heal orbs get stuck for one turn. On hindsight you can use Echidna on 9F to prevent healing, making it quicker. Two gravities, nuke, and two dark orb matches finish off boss easily. Gotta vent though: some facebook fan page said it can drop evolved form... 'twas a lie
Team RCV=2415. Average level=61. No skill up. It took about 20 minutes for this team to finish this dungeon. Until I arrived at the 10th floor, I had charged all the skills but Lucifer's morning star. I was going to use Lucifer's morning star when the boss's HP went below 50%, but I finished the boss before morning star became ready.
Snow Globe Dragons are maxed, LHD lv.65. Actually, any AOE can be placed instead of LHD, but that's what I personally have and use. Combo of two three-sized hearts heals a lot - enough to not be afraid of anything but the boss with her binds and multi-shot. Both Snow Globes deal nearly 50k to the boss - 100k every 13 turns, with LHD's active is enough to skip all the multishot phase if lucky. If not - Keeper of the Rainbow can save you once. Long but safe run overall.
