TT Card 362 (Gancanagh)

[Astrahime]

You can solo Eureka enough to get all the TT cards. Just do the weekly challenge log killing stuff near your level, and knock off the quests as they pop up. With just one hour a week you'll be there well before 7.0 drops.

Eureka Orthos is the deep dungeon, not the adventuring foray. The point still stands though, after all there is an achievement for soloing Eureka Orthos all the way to floor 100.
