Tyrian Ascendant [Greater Pact]

Prerequisite: Warlock, Sorcerer-King Pact class feature, Tyrian Bureaucrat feat
Benefit: In addition to regaining the use of your fell might, whenever you drop an enemy you have cursed to 0 hit points, each enemy cursed by you takes a -2 penalty to attack rolls until the end of your next turn.
    You can also expend your fell might to augment any power associated with this feat. When you hit an enemy with an associated power augmented by this feat, you also knock the target prone.
    Finally, you can use Charisma instead of Constitution for attack rolls and damage rolls with any power associated with this feat.
