This amulet is made from the scales of five ancient dragons. You gain resistance 5 to acid, cold, electricity, fire, and poison. If you take damage of one of these types from a dragon's Breath Weapon, the amulet begins to glow brightly; for the next 10 minutes, your resistance against that type of damage increases to 20. If you are subjected to a dragon's frightful presence, you can roll your saving throw twice and use the higher result to determine the aura's effects. This is a fortune effect.

Effect You exude an aura that terrifies all foes in a 60-foot radius, as the frightful presence ability with a DC 34 will save.
Traits
This rarity indicates that a rules element is very difficult to find in the game world. A rare feat, spell, item or the like is available to players only if the GM decides to include it in the game, typically through discovery during play. Creatures with this trait are rare. They typically can't be summoned. The DC of Recall Knowledge checks related to these creatures is increased by 5.
EnchantmentEffects and magic items with this trait are associated with the enchantment school of magic, typically involving mind control, emotion alteration, and other mental effects.
InvestedA character can wear only 10 magical items that have the invested trait. None of the magical effects of the item apply if the character hasn't invested it, nor can it be activated, though the character still gains any normal benefits from wearing the physical item (like a hat keeping rain off their head).
MagicalSomething with the magical trait is imbued with magical energies not tied to a specific tradition of magic. A magical item radiates a magic aura infused with its dominant school of magic. Some items or effects are closely tied to a particular tradition of magic. In these cases, the item has the arcane, divine, occult, or primal trait instead of the magical trait. Any of these traits indicate that the item is magical.
