Added usage (3.5e Feat)
From D&D Wiki
Benefit: Choose one class ability with a limited number of uses, you can now use that ability either twice as much or can use it 5 more times, which ever is higher. You can take this feat multiple times, but it applies to a different ability each time. (example- you can rage 6/day, with this feat you can rage 12/day)
Normal: you get the normal limits of use for the ability.
Special: if you only get to use an ability once a round or day, you may use it 1 additional time plus 5.
