The name of this Skull is the "Dominator".
It's a Legendary Speed type Skull that uses a living Evil Sword, a demon's Skull.
The Dominator uses the power of the Evil Sword to leave a 'Scar' in the air to attack enemies, and the Evil Sword absorbs 'vital energy' from those hit by the Scar.
When the Evil Sword has absorbed maximum vital energy, the Dominator can awaken the Evil Sword.
When the Evil Sword awakens, it temporarily cannot use skills, but its movement speed increases significantly and its basic combo attack changes to incessantly swinging the Evil Sword in a 'Madness' motion right where it stands.
When the Evil Sword returns to its slumber, the skill cooldown speed increases for a certain period of time proportional to the number of times enemies were attacked with Madness.
We are truly happy to finally create this Skull for our beloved little skeletons and patron Murdoc. The next 1.9.0 update will include the Dominator, along with some balance adjustments and bug fixes. We are targeting April 4th (PT) for the update schedule.
We look forward to your continued interest and support and hope you all have a wonderful day.
