Items

Interpose = Item can be used to block/deflect a blow. Any item with Resilience can be sacrificed to reduce the effect of a blow to half damage (no additional effects are reduced), at the cost of the item. If a character has proficiency with the item, it can be used to avert the attack and negate effects. A better than average hit is reduced to an average hit, and an average or less is reduced to no damage and no physical effect.
Resilient:

Durable:

Penetrating: The item negates 1 level of Resilience employed against its affects.

Pulverize: Does double normal damage to objects; if an item is used to interpose, the object will strip one additional level of resilience in its impact, in addition to the normal one.
