Guys,
I need your help. I want to be able to complete Keeper of Rainbow - Master, Room of Mask - Expert, Shine of Sprites - Expert because I need those evo materials. I have been trying but I keep losing and wasting precious stamina. Below are my best monsters. Surely I should be able to complete those dungeons, right? Any tip? Which team should I use, etc? Sorry for the long post.
For the Rainbow Keeper.
Titan as leader, to use resolve and a friend 5* healer (better if it's water based). Or use your Alraune if you have a friend with Viper Orochi or any resolve 50%.
Then, use 3 big dragons (the ones of 20k damage each one, specially the light one) and a creature with high recovery or that generate heal orbs, like your Shardran.
First round: Kill all enemies except one. Charge dragons during 15 rounds.
Second round: Dragon breath.
Third round: Dragon breath.
Fourth round: This is the most difficult. You will "die" each 3 rounds (but reborn because at 1 hp because of the titan skill). You have to get sure that you have 70% of your max life (50% if you have Viper Orochi) each time that the knight attack. So get sure to make a heal combo during those 3 rounds. Water healer is better than wood-light because it generate healing orbs (or add Shardran as fourth non-captain member).
Fifth round. This is like the fourth, but you have 5 rounds to recover 70% of life. If you finished fourth round, this is even easier (but longer). Probably you won't even need to match heal orbs to recover 70% of life in 5 rounds. In this case, simply make fast matches, use the breaths of the dragons each 15 rounds, repeat.
At least this is how it worked last week. But the chinese wiki show some changes in the enemy distribution.
About the Sprite Expert, you need a low level team with resolve. I use a green low level ogre, a green friend healer, 2 low level green chimera and 2 low level mystic stone knights. Target enemies with syncronized time. When there is a single enemy left, get sure that you have charged the powerup of the mystic stone knights to prevent lack of green orbs at the start of the next round.
You can get mystic stone knights on the Dragon Guardian expert challenge.
