Spell: Roar of the Dragon
You channel the might of dragons into your voice, letting out a roar that engenders respect in dragonkind but that instills fear in most other creatures. The impressive roar grants you a +2 circumstance bonus to Diplomacy checks for 10 minutes against dragons that were in the area at the time of casting.
@UUID[Compendium.pf2e.spell-effects.Item.Spell Effect: Roar of the Dragon]
Roar of the dragon affects non-dragon creatures with deep ties to dragonkind (such as a barbarian with the draconic instinct, a sorcerer with the draconic bloodline, or a member of a culture that reveres dragons) as if they had the dragon trait. The GM decides if a creature is aligned enough with dragonkind to be affected in this way. All enemies within the area other than dragons must attempt a Will save; to these enemies, roar of the dragon is a fear effect.
