Ah now I understand.
You aren't anywhere close to unlocking 'almost every skill' in the woodsman, slut, or slayer Archytype. You for one need to reach a certain level goal then unlock the stages such as "Slayer I" "Slayer II" all the way up to "Slayer V" each time you do unlocking more skills. In additional some skills have Tier 2 stages, such as the "Wolfs Rage" increasing the attack of the user, but once unlocked will unlock the skill "Pack's Rage." which increase the attack of the entire party.
The forestkin, lumberjack, and guard artchetypes all also have their own hidden skill, which players can only see once they buy the first 3. And since that takes gaining 75 AP on a handicap it might be nice to know what it is before hand.
All this confusion between us wouldn't have happened if there was a list by the way.
