Prerequisites Dragon StanceRequirements You are in Dragon Stance.
* This archetype offers Dragon Roar at a different level than displayed here.
You bellow, instilling fear in your enemies. Enemies within a 15-foot emanation must succeed at a Will save against your
Intimidation DC or be
frightened 1 (frightened 2 on a critical failure). When a creature frightened by the roar begins its turn adjacent to you, it can't reduce its frightened value below 1 on that turn. Your first attack that hits a frightened creature after you roar and before the end of your next turn gains a +4 circumstance bonus to damage.
After you use Dragon Roar, you can't use it again for 1d4 rounds. Its effects end immediately if you leave Dragon Stance. Creatures in the area are then temporarily immune for 1 minute.
Archetype Use
This feat can be used for one or more Archetypes in addition to the listed Classes. When selected this way, the feat is not considered to have its class traits.
Traits
Auditory: Auditory actions and effects rely on sound. An action with the auditory trait can be successfully performed only if the creature using the action can speak or otherwise produce the required sounds. A spell or effect with the auditory trait has its effect only if the target can hear it. This applies only to sound-based parts of the effect, as determined by the GM. This is different from a sonic effect, which still affects targets who can’t hear it (such as deaf targets) as long as the effect itself makes sound.
Emotion: This effect alters a creature’s emotions. Effects with this trait always have the mental trait as well. Creatures with special training or that have mechanical or artificial intelligence are immune to emotion effects.
Fear: Fear effects evoke the emotion of fear. Effects with this trait always have the mental and emotion traits as well.
Mental: A mental effect can alter the target’s mind. It has no effect on an object or a mindless creature.
