A suit of armor etched with this rune can create a bolstering magical layer that closes off to protect the wearer against dangerous environments. When you would take environmental damage, or when you enter an environment where you can't safely breathe, your self-sealing armor seals itself shut. It holds 1 minute's worth of air and grants you resistance 10 to environmental damage while sealed. You or another creature can take an Interact action to unseal it at any time. Once unsealed, the armor can't seal itself again for 1 hour.
Traits
Anything that doesn't list another rarity trait (uncommon, rare, or unique) automatically has the common trait. This rarity indicates that an ability, item, or spell is available to all players who meet the prerequisites for it. A creature of this rarity is generally known and can be summoned with the appropriate summon spell.
MagicalSomething with the magical trait is imbued with magical energies not tied to a specific tradition 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.
