Actually I started playing a fighter, but when I arrived in prison on the peninsula, already with a mercenary I faced a warlock. I had trouble I could kill him more. Then right in front next to another witch I chose when I got to level Sorcerer, and saved, and then save with the previous one magician. Wherefore I harmed, I did not get to them, but "changed" later. I tried to rest but can not be near by enemies.
Here is probably what is going on, based on my understanding. You had a PC fighter, and took a level of sorc, before or durring the battle with the warlock. What is your PCs charisma? 10? if so you will only ever be able to cast 0 level arcane spells. After a level up, you must rest to get access to the new spells. If you are to close to an enemy, you will not be able to rest, Move out of the area till you can rest, then go back in. Also, if your wearing armor, it will mess up the casting of arcane spells. take off the armor, (can't in combat) to avoid the cast failure from armor.
Note, unless you have a specific character build planned, taking levels willy nilly, Like a level of this and a level of that, will probably only frustrate you. a level 2 fighter, with a hench, could have probably closed to melee and killed the warlock faster than a fighter/sorc. it has to do with hit points, a fighter gets 10, a sorc 4 per lev, plus/minus the constitution bonus/pen.
