Heyo,

I sell my config of the MythicMobs bosses I created.
This code works with the version MythicMobs-2.1.9.
I coded them along with the RPGME plugin so if the bosses are too strong, you could just change the variables to a lower number.

NOTE:
ALMOST every ability has their own particle and sound!
To know which ability the mob used.
Also every boss has a health indicator and is getting displayed in the action bar.

There are 4 bosses;

Knight(Phantom):

Difficulty: Normal
Attack: Melee

Abilities: DirectStab, StunAttack, BombAttack
When the boss is on his 25% of health he uses his BombAttack to knock the players away from him.
When the boss is on his 20% of health he gets speed.

Modifiers:
This boss can't be attacked by arrows.
Speed of this boss is 20% less than normal.
The boss only attacks the player who's dealing the most damage.

QuickNote: Some swords have another lore on it. (The color will show how rare the sword is)
