Leveling Through the AgesLevels 1 - 10
Congratulations on starting up the game and making your first character! The quests from the time you get out of your respective starting area to until you move on are fairly straightforward. At level 5, you make the proud advancement of being able to make your first decisive skill point purchase!
From here, you'll be questing through either Nezebgrad (E) or Lightwood (L). At level 7, you'll be able to get your racial skill! If you are a Xadaganian, you can obtain this by seeking out Elizaveta Rysina in the basement of Yasker's Tower. For Arisen, you can get it from Negus Kheket on the top circle of Yasker's Tower. For Kanian's, you can find your racial skill questgiver, Ibor Yavorsky, in the top of Aidenus' Tower. I do not know the Elven NPC that gives the racial quest - if anyone can tell me, I will put it down!
At level 10, you can finally do XAES (E) or Oreshek Fortress (L)! This is an opportunity to finish up some World Mystery quests and also be able to get some neat gear if you're lucky. Also, congratulations on being able to pick up your first Ruby! Head to your trainer and buy it as soon as possible.
Levels 11 - 15
Once you are 11, you should be finishing up your quests in Nezebgrad (E) or Lightwood (L). Once you are, feel free to head over to IMD (E) or Siveria (L)! These are both fairly colorful but annoying areas. You'll be out of here soon, do not worry!
Other than that, these are some fairly uneventful levels.
Levels 16 - 22
You're so close to being able to move onto the fun and enraging parts of the game.. Hang in there!
At level 16, you should be done with IMD (E) or Siveria (L) and be able to move onto ZIT (E) or Frozen Frontier (L). Even better, you'll be able to get the 2nd partonage skill from one of the quests there so keep an eye out! You should finish up most of the quests in ZIT (E) or Frozen Frontier (L) and then head straight to Dead Sea (E) or Darkwater (L).
At level 20, you can go to Wild Isles (E) or Tenebra (L) and have some fun there if you've finished your World Mystery quests elsewhere. But don't move on without finishing those! They are
important. At level 21, you can head to Dream Factory (E) if you so choose. Sorry, League, but you're still stuck there!
At level 22, you can finally go to the Holy Land. Don't forget, finish up your World Mystery Quests and check out Laguna Boil (E) or Darkblood Citadel (L) for some instance-punching fun!
Levels 23 - 27
And now the fun begins! After you've finished what you needed to in the previous levels, you can head to a very scary, very fun place.. Asee-Teph!
Asee-Teph is the first zone you'll encounter with open PVP. There are gankers, griefers, campers, duelists, rompers - you name it. They will try and beat you down no matter what! If you are too afraid to PVP, you might want to keep your flag down and avoid War Banners like the devil.
At level 23, you'll be able to start running Lab 13 (E) or Castle Blight (L). You must, must, must do those! They have tons of World Mystery quests in them and will help you so much. At level 27, you'll probably get the World Mystery quest to go into TT1 (Tensess Temple 1). If you can get a group for it, by all means, go! If not, wait until you're level 30 or so.
Levels 27 - 30
A few more levels.. go, go, go! At this rate, you'll have moved out of Asee-Teph and into Eljune, yet another open PVP questing area. Things should quiet down from here on out so feel free to do whatever you please, flag up or down!
At level 30, you are able to move on to Coba Plateau. There are quests there in Nezebgrad (E) or Novograd (L) to help you transition into it. At level 30, as well, you'll be able to pick up your quest for the 3rd patronage skill!
Levels 31 - 40
From here, you'll be running your way through Coba Plateau for a while. At level 34, you should be able to move out of there and into Coldberg. Don't worry, things get better and you'll be so happy when you hit level 40!
At level 36, you should start looking into getting a group for TT2 (Tensess Temple 2). Then at level 37, you can be scott-free of Coldberg! Head on over to Avilon but don't worry, you're not there for long and almost immediately after you can head to Dragon Ring.
At level 38, you can go speak to Yasker (E) or Aidenus (L) and find out about how to get to Yazes Shard. This will be your last zone before you venture off into Gipat, woo hoo! Just keep hanging in there and you'll be 40 in no time.
Once you've hit 40, congratulations! You can talk to the postal worker and get a stone to port you to Gipat. Don't forget this, I hear you can't go there without it. Don't forget to do dailies either - dailies means more experience, gold, loot, whatever! They can be fun.

Levels 41 - 47
Technically, you're already apart of endgame now! But just in case we want to go farther, there's still 7 more levels for you! Welcome to Gipat, everyone.
At level 42, you can move onto Kirah. The rep there is great and you should be doing that as well as questing your little butts off. Don't worry, you'll be in Kirah a while - up until you're 46, actually! At level 46, you can go to Isle of Revelation. Do your quests, do your dailies, do everything you possible can. It will be a long while for you to hit 47 but once you do.. it seems like it'd be so worth it!
Once you've hit 47.. congratulations! Yet another endgame Healer produced through hard work and determination! I'm sure we're all glad to have you. As much as I hate to say it, you may toss this Caster Healer build out the window in favor of a more endgame-oriented build or even go Full Healer! Enjoy the rest of the game!
