What does it do?
This datapack is adding 2 bossmobs which are randomly picked to summon out of existing mobs. They are simple but still strong.
Sometimes a random Zombie or Skeleton is picked to convert into a bossmob. The bossmobs are equipped and have effects on them. Also they have a new loot-tables and drop way more EXP.
Datapacks good to combine: Kaths-Skillsystem. (see below)

Overall:
- 2 Bossmobs

World-/ Bossmobs are Zombies or Skelletons that turned into a Boss with extra effects and gear.
Drops:
- 1 Enchanted golden apple.
- 1-2 EXP bottle.
- 300 EXP points.
- 1 armor- or weapon piece they wear.
Bossmob attributes:

- Worldboss 1000-1024HP (500-512 hearts)
- Effects: Speed, Regeneration, Strength

Spawn chance an how to increase it
Default chance for every Zombie and Skeleton is 1/1000 | 0.1%
For them to become a worldboss there is a 1/100 | 1% chance on top
Change chance with this command:
/scoreboard players set Boss BossUUID {Value}
Default is 10
| Value | Chance | % |
|---|---|---|
| 1 | 1/10000 | 0.01% |
| 10 | 1/1000 | 0.1% |
| 100 | 1/100 | 1% |
| 1000 | 1/10 | 10% |
| 10000 | 1/1 | 100% |
1 score = 0.01% chance
Currently you can't change the chance for the worldboss.

Note for content creators:
I'm interested in seeing people playing and/or giving feedback on my Datapacks. So if you are creating a video of any kind with or about my datapacks, I would be really happy to get notified on my discord about it, so I can see your feedback. Also if you allow me to, I would put it on the Modrinth page, so others can see a first impression. This is not necessary, you don't have to!
