"Buy Only" And Quest Reward Skills

I just made a new ritualist loving it by the way but i've only got the skills i've earnt by quests so far.

Anyways, im having a hard time finding out which "cantha" skills i have got to buy and not earn via quests??

I've had a look around, even checked wiki, guru front page etc and some of the other forums i visit
but i cant find out which factions skills are "buy only" and which are given from quest rewards.

Wiki is either being updated or doesnt have this information yet so i thought it best to ask here

"EDIT"
I want to know which skills i need to buy so that i can buy them all and not waste gold on skills i can learn for free, obviously

Nice, im first to answer, and help someone out, cool

Anyways, there aren't any skills rewarded for completing a quest like in Prophecies except for the starting skills given by the trainers, the rest of the skills, for every profession, must be bought. So that means, once you got every skill given by the trainers in Shing Jea, all other skills must be bought. Sucks, but thats how it is. So that means that all but maybe 8 skills you will have to buy. Hope that helped. Again, skills are not rewarded via quests except a few at the start.

Thought so,

It's the first time through cantha with a "cantha born" character and i was a little miffed at first when i only got the first few skills.

I played through with a couple of my other characters and knew straight off that i wouldnt get any skill quests
so i just bought them all after reading on wiki /guru etc about it but when it comes to cantha born characters
theres only a couple of listed skills as rewards, theres some skills listed as rewards for the shing jea island
part of the game but nothing after that exept the signet of capture which i imagined would be there anyway.

Off to buy some skills then, Cheers
