It's a simple way to gather them by only having another character above level 21. So when you gather the Tier 1 Dragon Balls and call Shenron it will give you a capsule with Jacket Pants Boots a money Popo stone and the item that it is useful for indicating the dragon balls at the mini radar top left. So you can just attach to mail the item and send it to the new character. It will be useful only for level 21 and lower. In conclusion the most good example is my new character that is now level 33 and at level 25 i was having 2 dragon buff's HP and EP.

And this adds anything new to the ongoing dragonball hunting guideS?

I think yes!

Sorry, but you're not adding suggestions that aren't stated a billion times already. At this point, this is almost common knowledge and is practiced all of the time.
