I am not gonna ask this 1 more time cause I'm tired of playing dungeons because of this problem. HOW RARE IS THE GREAT CHANCE APPEARANCE IN A DUNGEON??? I played like 20 exact keys WITH ONLY 1 key run have a great chance. THAT'S LIKE 5 PERCENT???? CAN YOU PLEASE ATLEAST UP IT A LITTLE BIT???? My points are going to waste buying keys that are not resulting to great chance or EVEN A SCHEME DROP even on a EVENT UP days!!!

The "great chance" dungeon level spawns extra treasure chests in the dungeon. These treasure chests may contain valuable rewards. It's important to look for them in the dungeon that matches your character's level, so you're sure to get good stuff. But the other drops are not affected.
