Most important is to get big combos on 1F and kill everything in 3 turns. Susano max level, Siren max skill, Amaterasu 4100 heal. The return of Amaterasu Era

Echidna not skilled up; Susano max skill; average level 60
6.2

Average level 50. Ronia and the two rippers can be subbed for anything that helps kill faster. Slow but safe grind. On the boss, use the Keeper of Rainbow when he uses Immovable as Mountain, other than that, just heal if you need, and you have two active skills to help if you get heart orb trolled. Very safe

Didn't use Rainbow Keeper's skill at all, he's just there for extra HP and RCV. Archangel heals 1800+, all team average level 30. Boss took around 150 rounds to grind out. Meteor Volcano Dragon & Caol-ila were main damage dealers, very safe if you charge Caol-ila's skill before every floor. Keep 3 Hearts on the board every round against the boss, use Rainbow/Archangel's skills to save you if necessary

can swap for , super no-pressure. Faster if is max skill. If lacking hearts, use Orochi. Activate Orochi as soon as boss battle begins, average 20-30 mins to finish

Average level 50, having max-skill lets you play in your sleep
5.1.1

Average level 50, key is charging up skills before the boss. If you don't fumble, you'll sweep him, else he'll sweep you
5.1.1

A 9x attack team can easily pass, average levels around 40. Tough part is 4F, make sure you keep 3 or more Hearts on the board, recommend max-skill Isis. Don't run right in, charge up your skills whenever you see a Mid Ninja. Boss battle: Echidna -> 2 Gravities -> If full HP, sweep/If not full HP, fill up HP then sweep. You can finish in 2 rounds with 5-7 combos.
5.1.1

This team is super stable and fairly fast.
Average around level 30, the key is is max level +297. Take care to kill Light enemies on first floor, afterwards just make matches until Whiskey Dragon is ready. It'd be perfection if you swap for . Swapping with or can speed you up
Note: Swapping with might hit your team cost ceiling so swap for any low-cost Wood type (The whole team needs ~190 cost)
5.1.1
12116
RCV 1696... Basically neer lacked hearts at the boss... Flare Drall turns Wood into Hearts... Totally full after a combo... The only thing is that I had to use 's skill to heal once against the kitty and Light ninja... You'll never die =]

No skill ups at all, Amaterasu heals 2275, no pressure, but took 200 rounds to kill the boss
5.1.1
9405+
Dark/Dark Hades can be swapped for Hera. Amaterasu heals 3124 each round. Focus on killing Light ninjas on 1F, leave Fire ninjas/ogres for charging skills as much as possible to the next floor. Use skills on 4F, then charge them towards the end. If in danger on any floor, use Resist Dragon's blast, then charge it up again.

Wood type can swap for other high-HP Wood monsters. The important part is Echidna, she must have her skill ready before the boss battle, and use it as soon as the boss appears. If your luck is good, use 12x attacks for 5 rounds to kill him. If he's still not dead in 5 rounds, use Rainbow Keeper's half-damage skill and kill him in 7-9 rounds, or you'll have to use a stone.
5.1.1
10000+
A 12x attack team can win easily. Whole team average lv 30s, tough part is stage 4. If you can't sweep through quickly with 12x, then charge up skills slowly with 3x, and use Echidna if you're lacking Hearts. Use skills when the boss appears, if you're successful he'll go to heaven before he can make a move.
