ARIC'S WARRIOR GUIDE (spoilers)
Early Starter Tips (NON-Spoiler Version)Level 1 of Repair is fairly handy, though you can always teleport back to town. Level 1 of Identify and Lockpick should get you trough most of the catacombs, though neither are essential. Stun is very nice, but until higher levels, doesn't get applied frequently.
There is a bonus with Sword Expertise and Augment Damage (the male warrior's starting skills), where if you have level 1 and save/re-load the game, you will have each at level 2.
I saved in front of Lanilor's house and looted it a few time until I found a training sword.
