How does one set what skills a mob can teach? Trying to make a mob that players can talk to when they hit lvl 100 in a class to see if they have the force. All i see is a practice flag...

Do you mean to set a skill to a certain teacher? If so you just make the skill and set the teacher on that skill to the mob vnum you want to be able to teach it.

6Dragons modified smaug codebase has that teacher setting ability. I think Remcons LOP probably does too if you want to see examples.
