Im finally back with an update for this plugin, did you miss me?
Fixed:
Multiple Error fixes
Passive Wither Healthbar now updates
Respawning bosses will no longer multiply over time, finally found the issue
Added: Damage Modifiers for most bosses, some may work in weird ways due to Projectiles
Example of how to modify damage of a boss:
ZombieBoss:
enabled: true
enableSummonCommand: true
displayName: "Bob"
showDisplayNameAlways: true
DamageModifier: 1.0 //this is normal damage, add/edit this one to increase or decrease damage health: 50
spawnChance: 5
Hope you find the update helpful. As always, if you find bugs please tell me so over discord, im more active over there
