coreskills.yml lets you enable or disable individual mcMMO skills and sub-skills. Default values can be viewed on GitHub.
Changes require a full server restart.
The file uses a simple pattern. Every entry defaults to true (enabled) — you only need to add entries for things you want to change.
Disable an entire skill (all sub-skills):
Mining:
Enabled: false
Disable a specific sub-skill (leave the rest of the skill intact):
Acrobatics:
Roll:
Enabled: false
The sub-skill name used in the config matches the internal key name. The default file only ships with the Acrobatics example, but the same pattern applies to every skill and sub-skill.
The key names are derived from the sub-skill's internal name. If you are unsure of the exact key, check the source or experiment — an unrecognised key is simply ignored (defaults to enabled).
# Disable double drops from Excavation
Excavation:
Archaeology:
Enabled: false
# Disable Shake for Fishing without disabling Treasure Hunter
Fishing:
Shake:
Enabled: false
# Fully disable Unarmed
Unarmed:
Enabled: false
Enabled: false at the skill level) prevents all XP gain and sub-skill procs for that skill.
