The Angel Mummy is a mini-boss in Melody of Darkness. It, along with three others, must be fought to access Drachaos' chamber. There is no order in which to fight them.
The Angel Mummy is attached to the wall. It's upper head, a human skull, will spit triple fireballs, while the lower head, a dragon skull, will spit acid on the ground. They will detach for a short time when damaged enough, allowing the player to hit them easier. There is a platform to help hit the upper head. It has 1000 HP, and its theme is Resonance of Malevolent Souls.
