The short version of bob888's guide:
Use powerstrike + retribution as abilities.
Stat strength/vitality
A level 15 weapon with 70 ee does more damage than a level 10 weapon with 80ee. This is why you need to change weapon regularly.
Use either strength armors for more damage or ee armors for more defense. I'd recommend strength as it's usually cheaper, the higher the level of the armor, the more defense it has.
Be warned, it will be really slow at level 55+
Avoid using the marketplace for any purchase above 100 fg, most of the prices are enormous rip offs, ask the trade forum for a price check or just iso an item on the trade forum for a better price.
The marketplace prices are often done by traders who are trying to make a quick buck, we make them feel as uncomfortable as possible in LS, but they still turn up. the 100ee+ weapons in particular are all about triple standard prices on the forum.Once you've got the hang of it, the fastest way to climb is joining a group at level 1, however you WILL need gear from level 1 all the way to 55. here's an example of my dex/dagger setup:

If your goal is to make fg, in general the fastest earner is reaching level 55-60 then stopping yourself from levelling further by dying, as level 55 mobs drop just as well as 65+ mobs but are a LOT LOT easier to kill, by the time you reach 70-71 to MQ you'll see the difference.
