Activate 
command
Trigger You're affected by an area effect that requires a Reflex save, or you would take splash damage from a scatter weapon
Effect The blast suit locks together into a rigid bulwark, protecting you from the blast but preventing you from moving from your position under any circumstances.
You become Immobilized, gain a +2 circumstance bonus to your Reflex save against area effects, and gain resistance 5 to all damage you would normally take from area effects and scatter splash damage (this doesn't damage the blast suit). These effects persist for as long as the suit remains in the locked position. You can Interact with the suit to unlock it.
Traits
Something of uncommon rarity requires special training or comes from a particular culture or part of the world. Some character choices give access to uncommon options, and the GM can choose to allow access for anyone. Less is known about uncommon creatures than common creatures. They typically can't be summoned. The DC of Recall Knowledge checks related to these creature is increased by 2.
AbjurationEffects and magic items with this trait are associated with the abjuration school of magic, typically involving protection or wards.
BulwarkThe armor covers you so completely that it provides benefits against some damaging effects. On Reflex saves to avoid a damaging effect, such as a fireball, you add a +3 modifier instead of your Dexterity modifier.
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.
