Skillset
A Huge Wave of Zombies is approaching!
Passive: Instead of doing a basic attack, Dr. Zomboss summons a Basic Zombie to the frontline. The basic Zombie has X HP and deals Y damage with his basic attack. Zombies grant 1 stack of “Zombified” to the enemies they attack. Each stack of zombified slows enemies down by 10%. There can be a maximum of 5 stacks of “Zombified” in each enemy. If there’s an enemy with the maximum amount of stacks, zombies will rather attack other enemies. There can be a maximum of 5 zombie summonings in the battlefield. Zomboss and his zombies cannot receive stacks of “Zombified”.
Active: Dr. Zomboss calls in a Huge Wave of Zombies, removing all stacks of “Zombified” from enemies, and charming the enemies that had them for 1.5 seconds per stack they had, and granting the charmed enemies X basic attack per stack they had while charmed. The Charmed enemies now grant 1 stack of Zombified to the enemies they attack.
Jack in The Box 
Fantastic Damage
When a Basic Zombie is K.Oed, Dr. Zomboss calls in a Jack in The Box Zombie to the middle of the enemie lines. This zombie has X HP, and instead of attacking, it plays the jack in the box, applying “Distract” to all enemies while playing it. When the Jack In The Box is K.Oed, he explodes dealing Y damage to nearby enemies and stunning them for 8 seconds. There can only be one Jack In The Box Zombie on the field. This skill has a cooldown of 8 seconds.
Bungee Zombie 
Normal Damage
Dr. Zomboss calls in a Bungee Zombie, which will pick and take away from the battlefield the farthest enemy for 5 seconds. Then, the bungee Zombie drops that enemy, dealing X Damage, applying 2 stacks of “Zombified” and stunning them for 10 seconds.
Undead Intellectual
Enemies stunned while Dr. Zomboss is on the battefield receive 1 stack of Zombified.
Dr. Zomboss and his summonings cannot be charmed.
The Charm immunity might fail if Dr. Zomboss is above level X.
Brainiac Maniac
Now, Dr. Zomboss basic zombies will be summoned with a shield with W HP. When the shield is destroyed, the Zombies gain +50% attack and movement speed and Basic Damage.
Every time an enemy is disabled, Dr. Zomboss grants himself 1 stack of Hardy.
