Guy posted a cool strat he used for Hera with the dark mystic dragon.
Basically use a damage type leader until the boss fights start at stage 5, then swap dragon to leader for double damage reductions and sleepwalk your way through.Basic structure of the team:
Laphroaig(helps if skill is maxed)
Echidna
Lilith: make sure to awaken her at least once for auto heal
Nebradisk
and any filler for you want since Siren isn't really needed for this team.
Friend GOdin: awoken to at least the auto heal
Dungeons 1-4 charge all abilities and use as needed except for Nebradisk.
Once you get to Venus, use Nebradisk's skill and she shouldnt hit for more then 1000 damage with Nebradisk's and Odin's Leader Skill. Just make sure to match orbs so the heal can take place. Poison every stage including and after Venus(makes it a shorter grind)
You'll find that auto heal heals all of your HP before each and every hit of every enemy. Just keep matching orbs so that it can happen.
Time: ~40 minutes
Literally fool proof unless your're not good at comboing. Just need to combo 3 or more and charge nukes through stages 1-4 Hope everyone can use this method for the next time Hera comes around. Nebradisk is a very useful monster
