A magus gets: dancing, flaming, flaming burst, frost, icy burst, keen, shock, shocking burst, speed, or vorpal as options to enchant his weapon. There are archetypes and arcana like ghost touch that add more options, but does the base magus get any more variety?
I know that new books introduce new magic abilities all the time and just wandered if a magus will get any of the new options. For example the corrosive ability gives +1d6 acid. It fits nicely with the other abilities and makes sense for a magus with corrosive spells. (I don't know if the Magus or corrosive came first it is just an example of an ability that could be added.)
