When you have decided what weapon you want to use learn the skill which allows you to use the weapon more better.
As a mage or survivor you would probably want to use a light weapon,like a spear,some swords,daggers and for a survivor a bow.
Survivor is probably easier due to the deadly gift skill.
I would say know creature is good to get the hitpoints of a monster(for a fighter/survivor) but as a mage it would be helpful to get know creature to the max as it shows the resitances.
