Lvl up your bow early... it is a great way to damage a mob before melee... as a lvl 14 thief being able to do 25 - 35 damage per shot before mob gets to me is very valuable
and speaking on that note, i did not know this when i began and I hope this helps some people out:
when you are leveling, the only way to max your skill is to attack something of even con, and all the skills seemed to have a certain cap against what con mob you are fighting.. when you max out your skill for that lvl it turns blue.
Now i admit im only lvl 14 now, so this may not be 100% accurate, but fighting decent cons seems to stop giving skill ups at a certain point, then when i fight an even con i go up again untill skill turns blue.. tough to do, but necessary, and another reason to group.
