I'm guessing that the final entry for Focused Expertise will look something like the following:
Focused Expertise
Focused Expertise
Benefit: Choose a weapon that you can wield as an implement. You gain a +1 bonus to attack rolls with any implement or weapon power you use through that weapon. The bonus increases to +2 at 15th level and +3 at 25th level.
Even if a weapon qualifies for this bonus more than once, you can apply the bonus only once when using that weapon.
Special: You can take this feat more than once. Each time you select this feat, choose another weapon group.
This bonus is not cumulative with the one provided by Implement Expertise or Weapon Expertise.
