Weapon enhancing bonus acting as special material

[gnrrrg]

I don't use a lot of magical weapons, so I'm not sure if this is a real rule or just a home rule someone used, but I was recently told that different weapon enhancements will give a magical weapon the properties of special materials - e.g. a +2 weapon will act as cold iron against fey and demons.

I looked in all the places I thought it would be obvious that such things would be listed (under special materials, under costs for weapon bonuses, etc)in both the CRB and Ultimate Equipment but couldn't find anything specific. The person who told me about it said that there was a table that told what enhancements did what, but I can't find a table that does this either.

The closest I could find was for individual materials such as mithral weapons will act as silver against lycanthropes, but I'm pretty sure that is not what they were referring to.

Does anyone know where such a list is located?

It is a real thing, but yeah, no idea WHERE it's listed...

Under the entry for Damage Reduction maybe?

Quote:

Overcoming DR: Damage reduction may be overcome by special materials, magic weapons (any weapon with a +1 or higher enhancement bonus, not counting the enhancement from masterwork quality), certain types of weapons (such as slashing or bludgeoning), and weapons imbued with an alignment.

Ammunition fired from a projectile weapon with an enhancement bonus of +1 or higher is treated as a magic weapon for the purpose of overcoming damage reduction. Similarly, ammunition fired from a projectile weapon with an alignment gains the alignment of that projectile weapon (in addition to any alignment it may already have).

Weapons with an enhancement bonus of +3 or greater can ignore some types of damage reduction, regardless of their actual material or alignment. The following table shows what type of enhancement bonus is needed to overcome some common types of damage reduction.

DR Type Weapon Enhancement Bonus Equivalent
cold iron/silver +3
adamantine* +4
alignment-based +5
* Note that this does not give the ability to ignore hardness, like an actual adamantine weapon does

I did not think of looking there. Thanks to all who answered.
