FCPBP characters are allowed to have Attack/Damage and Defense/Toughness tradeoffs up to +/-5 in any direction. You may have different tradeoffs for different attacks if you choose.
A minimum of 1/3 (rounded up) of a character's total Attack and Defense bonuses must come from Base Attack and Base Defense, rather than feats like Attack Focus or Dodge Focus.
A character's Grapple Bonus is capped at 3x PL, regardless of source. A character can have powers that add to their Grapple Bonus (such as Elongate, Super Strength, etc.) beyond what would cause them to hit that cap, any additional ranks beyond the cap simply will no longer increase the character's Grapple Bonus.
