"Risk" and Savage mode
The Risk increases as you continue to fight strong enemies in succession.
(Flame icon at the top of the screen, % notation)
When the Risk exceeds 100%, the adventure enters Savage Mode.
In Savage Mode, the number of enemies and elite monsters will increase.
In addition, equipment, skills, runes, and treasure chests of rarity 6+ (★★★★★★~) will only appear in Savage Mode.
The Risk decreases when moving rooms or when the battle is prolonged.
