I got lucky with my first abyssea party. I had an ls buddy who invited me. Went from lvl 72-99 in a few hours. It was a cleave party so mad xp in altepa.

Oh another thing, you could make mad gil if you lvl leather craft to 30. Went to teleport-mea and farmed dhalmel hides. Had a stack of cluster, windurs tea leaves, and distilled water. Make dhalmel leather and sell for 100k. Materials will cost 5k per stack and profit margin of 95k. I farmed as thf/bst for widescan.

Once you get to lvl 90+ pick a main job and try to pimp it as much as possible. At one point I was trying to have 3 mains but it ended up costing too much. Thief is my main but since beast is much better for solo I am pursuing that too. Everything else is just to be more versatile. You won't get empy, mythic, or relic on every job you hit 99 with. That is a long term goal and would take years to accomplish if you pick many to pursue.

Don't be afraid shout for help. Chances are you will find a couple of bored people or who need what you need.

I had to send /tells to random people help for lb 95.

Make lots of friends. I usually duo with a smn friend of mine that I met through a casual ls. We kill a lot of nm's together.

Some jobs have nice weapons you get from trial of the magians. Beasts had nice axes that increase evasion and another set that increase physical damage resistance. Look up these weapons for your job and determine if it is something you want. If it is than get started as soon as you can.
