Honestly I play'd this game for a good amount of days. I made it to Veteran Rank 1 and decided it's extremely hard to level up from here on out.

The best thing to do at this point, is constant grinding on quests. Or dungeons.

Discern almost hit it there. Best way to level up is either being a VAMP or a WW then go into Dungeons and do higher level Quests/Missions. I hit Vet 1 after around 4-5 days. Once you hit Vet...its a hell of a lot harder! Bare that in mind.

Farm old orsinium or cracked wood cave won't take long I got vet 16 in a week just very boring you will need xp pots aswell

Starting new the best way to level up quick is doing quests in the area either your level or one or two higher than you. Do the occasional dungeon but stick to the quests.

Dunges brah.

Just seen these replies, thanks guys.

1) Do all SIDE QUESTS BEFORE moving into the next area. By this, if you are level 1, stay in the first map onto you complete all the quests in that map. This will reward you with the most XP for your level. If you are level 40 trying to do a level 25 quest... you are not going to get that many XP points.

2) Farm "something". One thing that I am doing is stealing armor / weapons from the fighter's guild and I am destroying them for XP and materials. If you are in a guild with an active guild store, you can actually make $$$ of it. Example, I farmed cotton and made over 10k within a few hours.

3) Get in a group and complete quests together. This is the fastest way to be honest. You will die less and complete quests faster.

I personally do all the side quests in an area before moving up to the next. But in my experience, dungeons, quests, and some pvp quests/objectives have all been pretty good for leveling.
