Here's the price that I got from the great key so far after spending 2300k coupons.

Kakashi Shonen = 24 frags.

Minato Hokage = 11 frags.

Masked Man = 4 frags

Mt myoboku grasp = 134

Coins = 90k+

Medium refinements = 14 pcs

Seals scrolls = 5pcs

Mood scroll = 15

Okay, so here's the thing. I'm trying to get Kakashi Shonen for Minato Jonin. But I only got 24 frags of him. Oh, well. I'm back to saving coups and again. I'm going to regret this someday. Lol! Pls. fix your events Oasis. Consider your f2p players. PLEASE!
