By Kai-Yol@PF: Basic strategy, just red tpa and clear away as many other non-red as possible each turn trying to conserve other reds for next turn. Can survive 1 shieldra hit at a time, so if there's two on screen try to make 2X4 red to kill. Goblin for quick orb change as needed. ~185k points from rarity alone. Good luck.
By ☸ Shelli Δ: S-RANK TEAM: Lead with a 50% dark reducer, pick a friend leader that is an autohealer, add subs to total no more than 20 rarity, and then grind your way through! You've got this on rarity alone, so you don't have to worry about number of combos or anything. You should never be in any danger of death. Enjoy your Tama!
By milkyway: Easy S rank build. Just match four light orbs every turn to get TPA. Use valk orb change skill as needed. My valk was max skilled, friends was level 4.
By Emi: S-rank by rarity. Can be any 1 stars. 3 star is a stats stick. Go for non-drawn-jokers first. Their armor makes them a bit tougher. Probably can be done with other Amaterasu UEvos also. Build Gungnir back up inbetween floors!
By Curtis: Use skills in case of synced monsters. Otherwise just grind down and enjoy the Tamadra. S rank on rarity alone.
By Avelarius: Easy S-Rank - Rarity alone.
High HP and Recovery plus half damage = Take your time.
Grape just in case, Lilith to speed up Shieldras.
F5 - Hades/Hamahime and grind.
By Greg: 3.5x ATK from Meta and 3x ATK from Valk makes for an easy build, easy dungeon. Plowed through; no stalling for skill up etc. Meta lvl 83, Echidna lvl 47, shynee lvl 47, lilith lvl 71, HHA lvl 89. All fully awoken.
