Astral

An example of an Astral ability is the ability to conjure up a mallet. After adding
on the 1st add on, the mallet is able to create an explosion after being hit. Adding the
2nd add on will allow the opponent to spin away after having a direct hit by the mallet.

In the world of Gaia, about 60% of the population of the world are able to harness the inner ability within them, dubbed "Astral". People who are able to harness this ability will always start of with a base ability or item. As they train and hone their skills, eventually his/her 1st add on will be unlocked.
The 1st add on is obtainable through vigorous training. But for the 2nd add on, one must fulfill a certain condition for it to be unlocked. Some will have to have to have a strong will to be stronger etc.
One could use both add on at once and in any order as they will it, or none at all. There may be many people in the world that may share the same add on as your Astral, but the effects will differ within each person.
