There are a few ways to train on this site one is by yourself. When you train this way you have one option write out a story like training session describing what all your char. did to train and at the bottom place amount of time the training took!
The other form of training is of course Sparing with another friend you may do this to a limt of three times a day. Once you have completed the Sparing session email it to a Moderator and
display how long you sparred. As a note when saprring regular battle system rules do not apply! and no one dies in Spars
One Last way to train is to Battle in a non death match with a reff this way you get a major power increase without dieing!
