Along with
Alignment,
Skills
are central to your ability to effectively perform higher-level actions.
Without the Skill, or if your Skill is not at an advanced-enough level,
Stealing,
Healing,
Tracking,
or performing the other higher-level actions which bring you the most
Experience
are very likely to fail.
Skill teachers are everywhere in TriadCity.
Some are better than others.
Some will agree to teach you, others will teach others but not you.
Some demand payment, sometimes in quite esoteric forms.
In TriadCity learning is a life-long necessity.
If your Skills stagnate, so will your character.
