Works on WIS for 1 feat
Unskilled: Character is completely unsuitable for the task. Example: Wizards and Command.
Skilled: Character has some skill, but it's not his primary focus. Example: A fighter sovereign that has never shown much interest in Administration.
Expert: Character is very skilled for his level; this within his area of expertise. Example: A multi-class noble that has maxed out his ranks in Warcraft.
Master: Character has pursued the skill with singular focus; he has max ranks, one or more feats to support it, and a good ability score keyed to that skill. Example: An expert who has maxed out his Admin skill, his Int, purchased Skill Focus (Admin) and a regional feat giving a bonus to Admin.
I've ripped these lines from different posts from the GM's. Its not a big issue for them, but I suppose we players like to geek out on these details.
