Hush

After concentrating on the image of a calm prairie, you release a subconscious twinge to all nearby creatures, making them as silent as an elven pickpocket.

You send out a subconscious twinge that causes one or more creatures of 4 Hit Dice or less to be as silent as possible. Creatures with the fewest HD are affected first. Among creatures with equal Hit Dice, those who are closest to the power's point of origin are affected first. Hit Dice that are not sufficient to affect a creature are wasted. They cannot speak, intentionally pound on something to make a loud noise, etc. Creatures affected by this power cannot cast spells with verbal components nor use bardic music.

Augment For every 2 additional power points you spend, this power's range increases by 5 feet and its save DC increases by 1. In addition, for every additional power point you spend to increase the range and the save DC, this power can affect targets that have Hit Dice equal to 4 + the number of additional points.
