Enchantments are minor abilities, like skills but closer to just things that a character can do. However, they are very minor in nature.
There is not yet an Enchantment progression table. So go ahead and post one if you want one.
However, the difference between Skills and Enchantments is mostly in the power level involved. Most Enchantments are passive abilities, the sort of things which are so minor as to always be considered "active", but they are MINOR is scope or strength.
That's about all I know at the moment.
