Possible Changes/Additions. Thoughts?
Deals 1d6 damage at first level. Increases by +1d6 every other level.
Adept & Master Abilities.
At 1st, 2nd, 4th, 6th, & 8th level a fighter may choose a special ability from the list below. Each ability may only be chosen once with the exception of the bonus feat ability which may be chosen any number of times.
At 10th, 12th, 14th, 16th, 18th, & 20th level the fighter may choose a special ability from the list below. Each ability may only be chosen once. If he chooses the fighter may take a special ability from the Adept list instead of a Master ability.
I'll come up with more ideas for Adept & Master abilities, but I think these changes to the class improve it overall.
