These are my two fastest runs from level 1 to 50 and I did them both different ways.
This is from Colorado, on day 16 I hit level 50 and it was by going pure trapping from the start while collecting the best possible 'setting traps' gear, once I unlocked the job 'hunting grizzlies' I put some points into 'leadership' to unlock the job 'construct' manor house.
Also, collecting the gents set along the way helped in all the best XP quests up until this point.
It must be noted though once you get to a certain level, maybe around or just after level 50 you will be required to respec these points out of 'setting traps' into better skills such as shooting, hiding, stamina and appearance but money is not so much of an issue for this character build as all you do is jobs all day long.
This is from world 2 where on day 12 I hit level 50 and it was by placing all skills into dueling skills I went with a pure offensive melee build (aim, dodge, vigor & appearance), this helped greatly as I was flying through levels daily and never ran out of energy points once.
Must be sure to set to sleep when you are offline or you will get KO'd and then this method is void, must have previous dueling experience and be selective in your targets, also this works best on developed worlds where there are plenty of high level non duelers to take advantage of.
With the pure strength build you have great HP so it is near impossible to KO yourself, also to note you need to be buying plenty of duel motivation boosting items so it is a good idea to join a large alliance where folk can help you with attaining these items, although low level crafting as a tonic peddler allows you to craft filtered cigarettes easily enough which offer +7% duel motivation.
It is quite easy to complete the majority of the ghost town and kate's wedding ring quests with this build.
elmyr was in no rush to level up as fast as he could. we know, as it's been done, that you can do it in less than a week if you try really hard.
Yup lol, speak to GaGa, she is freakishly awesome at power leveling
