What's the quickest way to level in Dragonica without spending real money?  Seems like in the beginning there are about 7 or 8 areas of purely grinding and one or two areas of quests... and further along the road there are mobs that are level 10 and up

you can hit lvl cap without ever touching the cash shop.  you will just lvl slower than those who fork cash to improve their weps with security scrolls.

Ok, this is what I did and i got to level 25 on the second day.

Do all quests until level 5 or 6. Get your gear updated.

Keep on doing Vagabond mission quests until about level 9 or 10.

Then from there, just keep missioning.

Played this game for some days and then uninstalled.

Running the missions with people is fun....until you get to the point where you have to run the same one 50 times in a row to get a level and there's no new higher level ones to do.  

This happens around level 33.    You can then move on to something less fun, solo field grinding for devil soulstones.    I wasn't interested in doing that, so that's where the game ended for me.
