Ok -- the next time I have the chance to obtain additional skills I will try this but I don't see haw it would work as a wizard... I am surprised that there isn't a lock picking spell for the wizard simular to the spell in Baldur's Gate...
Why should a Wizard not be able to learn how to pick lock? Why should a Survivor not be able to play dead? Why should a Warrior not be able to call for a blessing? It might not be a traditional skill for the class, but it's a learnable skill none the less. If you were playing as a purist (one who only learns skills form their own class), I could understand.
The skills are structured so that there's one of everything (for the most part) and not simply a double up that uses a different resource (e.g. Mana instead of Lock Picks). It makes sense to select the majority of your skills from
The Way of <Your Class>, but over-specialisation causes weakness.
