Confounding (Racial Power)
Once per battle, when you roll a natural 16+ with an attack, you can also daze the target until the end of your next turn.
Champion Feat: Instead of being dazed, the target of your confounding ability is weakened until the end of your next turn.
As a standard action, at-will, you can create a strong smell or a sound nearby. Nearby creatures that fail a normal save notice the smell or sound. Creatures that make the save may notice it but recognize it as not exactly real.
