Guys the Final Rewards are not worth it to farm 4000 Fireworks especially with that abysmal Drop Rate from Phase 1.

My advice: Wait for Phase 2, get at least 2000 Fireworks and your Event Girl is maxed out. Do other stuff this week like Leveling, Dragon Farming, Manyu Farming etc.

That's what i do cause 5 Ampys from each Type for 4000 Fire Works is all you get besides the Maxed Event Girl^^

And that's not worth it in my book^^
