Remember it's best to kill mobs during the weekend (2x exp points). Also, try to join some XP legion for a little exp boost.
1-9 - Get your Marchutan weapon. Remeber you can take only 2 weapons, so e.g. ranger take 2x bow and fuse it at level 10. Kill mobs in Ishalgen, follow the path to Munin. At lvl 9 do the Ascension quest.
10-21 - Create your new weapon. Add manstones, Idian and a Godstone. Enchanting your weapon is optional. Use Berdin's amulet, kill mobs in Altgard. Start in the Black Claw Outpust, follow the path to the Zemuru's Grave
21-25 - use Berdin's amulet, kill mobs in Morheim, Taran's Cavern
25-27 - use Berdin's amulet, clear Nochsana + quests
27-35 - campaign quests
35-40 - use Venerable Elim's amulet, clear Alquimia. Don't do regular blue quests, waste of time. Do only the pink quests.
40 - pink quests Alquimia and Steel Rake
40-43 - campaign quests
43-45 - regular blue quests in Beluslan at the Hoafrost Shelter, use Tea of Repose, it costs +/- 1.5kk each on the broker
45 - Campaign first. then the pink quests. Not the other way around. After that, Adma solo with Berdin Amulet
46 - pink quests Draubnir (don't do pink Draubnir quests before lvl 46 because quests from lvl 40 and 46 overlap each other)
50-53 - campaign Gelkmaros
53-65 - use Venerable Elim's amulet, 6x BT solo, 1st boss only. Boom, you're lvl 65, congrats!
