I'm level 42 and I never completed the DB Quest for lvl 1-20... A friend told me this effects the drop rate of the real DB's, which explains my other friend and my luck.. Anybody know if this is true or not, and if so, show me where I can find the quests? I have 5 fake ones right now.

It isn't true. But incase here are the links to the locations of the quests

Getting the real dragonballs is pure luck. Trying fighting high level mobs, the higher the lvl the more of a chance. Feel free to thank me

its do increase the rate of db in some way you will get a dragon ball chip from shenron that tell you which mobs may have a dragon ball droped

I bought the radar before, but I think it does increase the chances. Before when I didn't complete the quest DBs, I got nothing. Now after I completed it, I actually got one. xD
