Hello all,

I've been looking for specific rules which explain the wording of Damage Resistances and Vulnerabilities:

Lots of resistances will specify "Bludgeoning, Piercing, and Slashing from Nonmagical Attacks", but resistances like Skeletons have will only say "Bludgeoning". The fact that any type of Bludgeoning damage counts is implied, but is this explained anywhere?

The general trend in 5th edition is that a feature does what it says and nothing more (or, in this case, nothing less).

In your example, the Skeleton has vulnerability to bludgeoning damage, regardless of source or said source's other traits. It will get double the damage from a normal club to the face, as well as from a magical hammer, as well as from the bludgeoning part of an Ice Storm.

The same applies to resistances. The barbarian, for example, gets Rage, which includes "You have resistance to bludgeoning, piercing, and slashing damage." It doesn't care if that damage is magical or not.

For reference, see Player's Handbook, page 197, or here.

Considering there are cases where some things are explicitly resistant to damage from non-magical sources - it is clear that if a resistance/vulnerability doesn't explicitly say "non-magical" it means they are resistant/vulnerable from all source of that damage type.

Thank you. I will keep this in mind when I face any more Skeletons.
