Print this Some basics but helpful
I am pretty new but know rather a lot about the game so here are some basics
Never,ever have a rookie on full happiness all the time I assure you it will evolve into numemon.
To get a rookie to evolve to a champion just get 1000+hp and mp and everything else 100+.
Champions: I advice you should train all the time till the digimon is about the age of twelve,this time you should have happiness full to make them live longer.
Happiness makes them live longer use it apart from on rookies!
If you try to feed something to a digimon and it refuses scold it instantally,
Happiness does not go down just disc increases,then give it to the digimon again it will accept.
Sukamon:yes everyone complains but train one to it's very limits with full happiness and as try not to have to many care mistakes and you may get a good digimon,i always get numemon with about 4800hp and mp and 450 of everything else
One final thing for treasure hunt pay for it then sell stuff you get always end up with more money!And trade with the digimon(can't remember their names) in iceland.
