I still play it, got the best luck in this game so I now have all the 6 stars in game. ...
The event is a bit confusing I think. Not sure if I farm it correctly at all.
That's amazing luck. I've had some luck but still missing a some of the 6*. Managed to pull Chen off the Hellagur banner.
Yea, it's a bit confusing. This is what I've gathered so far...
Farm OF-7 for Fiesta Obsidian to around 2400 then the dailies should fill out the rest. Use those for the mission milestones.
Farm OF-8 for Festival tickets to use on OF-F4 for Festival Tokens. Use the tokens on the Capsule Machine.
Tons of farming in the event but the payout is amazing.
