Ancient Ravenous Dragon

The Ancient Ravenous Dragon is the final boss in Live Dungeon (the video game). It appears on floor 100 in the Fortress of Lost Memories. Every physical attack on and from this creature lowers the durability of the players weapons and armour, making ranged attacks the preferred fighting style against it. However, it is weak to the Holy attribute, which allows the healer to attack it with healing magic.

Once Kyotani Tsutomu is transferred into the game, he sees the Ancient Ravenous Dragon again. However instead of defeating it this time, it easily defeats him with a poisonous breath attack.
