VDO is the online solo play between the Claw Gladiator and the Devastating Dragonlord. The online mode that is designed for multiplayer makes the dragonking's HP double.

None of the heal stones is consumed in the battle. The HP recovery is executed from the Hurtconverter, a gladiator's skill that converts all attacks to the enemies to HP back to the player.

At the end of the online battle, the game offers the player a multiplayer bonus. This online map doubles the reward items.
