its basically like a little cheat you can use to lvl up fast that is now legal in game so everyone uses. just create a team with your friends, gf or make your own. but it requires dedication and a bit of time. making sp to use if you are to afk and getting advanced electronic remote from the item mall. unless you plan to sit at your computer and manual train

unhappy or confused with those then just Google a couple more.
Keywords like, wlo gst, wlo gs training, wonderland online burst guide, wlo goddess skill training. etc... or enter the element you are and search for separate guides on those.

also when you lvl igg rewards you with lvl up packages you can get at certain lvls see here; http://wl.igg.com/event/gift1/

choose what server you are in and it'll send the items to your character next maintenance as long as you submit before Sunday to give the system time to register your claim.
