This dungeon has two difficulty levels: "Mythical" and "Legend". The final boss is Awoken Hera-Ur, the fire-type version of the original popular God-Type Hera. She gains a dark sub-type upon evolution.
A leader for a 9x Devil Team, which is lower than Satan's 12.25x but can have positive RCV. Currently there are many strong Devil subs with a good variety of skills, so she should become a popular leader.
Dual-Attribute Enemies
This dungeon contains a "Dual-Attribute Enemy" system, new as of game version 5.3.
When a dual-attribute enemy appears, its HP bar will display two colors. For the first 50% of its HP, it will be the main attribute color, but when its HP drops below 50%, some graphical effects will appear and it will change into its secondary attribute color. The enemy's damage and resistance will be based on its current attribute.
