The Overseer-Its a Regular boss..Oh wait,or is it?
The Overseer is an Supportive Boss,Being most dangerus out of the variations if npcs arent. around,really.isnt much of a Problem,The npcs are.The more npcs are near him,the stronger he gets.At a point where he KILLS ANYTHING NEAR HIM and No longer needs any npcs near him for buffs.
His colors will change.Can max have 10X of his hp,3X dmg.even 5x speed. (If an enemy is a flying enemy this variant wont work due to it prolly being unbalanced.)
The next one is a support.
Mechanical Bugler-Its a support.
Mechnical bugler has a Giant con,Its that he.Deals Way less damage for 2X Hp and 3x speed.(his damage is maxed at 0.5X) meaning he deals way less damage.
He Randomly does these ablities.
the first one heals ANY Npc that are On His Team/Side (that means that other npcs that Arent wont get healled,those that got their team changed it matters too).
The other one just speeds other team/side npcs.
