Mentor – General
A character who takes this feat has offered his knowledge and skill to a lower-level NPC and takes that NPC on as an apprentice.
Prerequisite: Apprentice , 5 Ranks in at least two of the four skills associated with your Mentor Category [See Below], Must have graduated from an Apprenticeship.
You gain a number of apprentices equal to half your character level. You can bring one apprentice with you on your travels, however you are able to exchange apprentices when in town. These apprentices are treated as cohorts except they are 4 levels lower then you.
If using the rules in ultimate charisma, you can take the improved cohort perk multiple times, however they can not exceed your character level.
