Skill Ranks, Class Skills, and Training

[SirCorius]

There seems to be a disagreement in my group. Everyone is telling me that I cannot take skill ranks in a skill that requires training to use unless it is a class skill. Basically they are saying I can't take skill ranks in linguistics, knowledge planes, or Knowledge religion as a sorcerer. Is this accurate? I find nothing in the rules that support this and it is pissing me off since it is holding me back from languages and prestige classes.

There is nothing preventing it, the only thing is you don't get the +3 bonus for it being a class skill.

Requiring Training just means you have to put at least one skill rank in the skill before you can use it.

Page 86-87 of the CRB describes how all this works. No where does it state that you need to have a trained only skill as a class skill in order to put ranks in it.

They are probably mixing it up with the 3.5 rules on skills.

[Seranov]

Your group is incorrect. In 3.5 you had to spend twice as many skill points to get each point of skills that were not class skills (which might be where they are getting this idea), but in PF you can go 1:1, regardless of whether it's a class skill or not. Being a class skill just adds a +3 bonus and nothing more.

[Rynjin]

They're wrong.

Like, way wrong.

The wrongest.

You should be allowed to add ranks to any skill by the rules, but perhaps your DM is using house rules? You should talk to your gm and figure out why he is saying that.

I have played with GMs who won't let me add a language with linguistics unless I do something in game (like find a teacher or buy a book) and spend some downtime on learning it. (And some languages are harder to find teachers for, too.)
