damage reduction

[glass]

Well none pointed out that any creature with Dr can pierce same type of resistance with its natural weapons. (Cant remember but i think it has to be natural resistance not gained by spell. But there may be flaw in rules)

That means forexample werewolf (it has dr/silver) with magic fang could pierce dr/silver AND magic. Therefore certain summon spells might do the trick sometimes !

No. Creatures with DR/Magic can overcome DR/Magic with their natural weapons, but it is not a general rule.

Also, creatures with an alignment subtype can overcome DR of the opposing alignment with their natural weapons and with any weapons they wield, regardless of what DR they have. EDIT: Actually, as Staffan points out below, this is the other way around. Oops!

Actually, DR of the same alignment, which is usually possessed by creatures of opposing alignment. E.g. a devil's weapons are considered Evil, which will bypass the DR 10/evil of the Good hound archon.

Yeah, sorry, that!

"DR 10/silver and magic" means that WEAPONS (including natural weapons, unarmed strikes, and improvised weapons) used against the vampire deal 10 points less damage unless those weapons are made of silver (or coated in alchemical silver or a silversheen elixir, as described in the 3.5 PH or DMG, I forget which) AND also possess a magical enhancement bonus to attack (whether it is a magic weapon normally, or just received a temporary enhancement bonus from a magical source, such as a Magic Weapon or Magic Fang spell).

Spells, energy effects (including things like lava, acid pools, cold damage from freezing water, alchemist's fire, the Shocking ability of some magic weapons, and so on), spell-like effects (including psionic powers), and supernatural effects, all ignore Damage Reduction. So a vampire can be thrown into a furnace and WILL burn just as easily as a human would, though he'll probably be ticked off when he flies out of the flames and comes to kill the offending adventurer.

DR with a special material in its description, such as the "silver" in a vampire's DR, DOES NOT confer the creature to bypass that same DR type. So vampires cannot hurt each other very effectively with natural weapons; they'll be dealing 10 less damage to each other because of their Damage Reduction. Likewise with regards to werewolves; they deal pitiful damage to one another in unarmed combat with tooth and claw, because werewolves' DR is only bypassed by silver (when making physical attacks; as noted already, energy and spells and such always bypass DR). A magic weapon wouldn't hurt werewolves or vampires as well as it would hurt humans, unless that magic weapon were also silvered.

However, a vampire's natural weapons are considered to be magically enhanced for purposes of overcoming Damage Reduction; DR X/magic (or DR X/some-material-or-alignment and magic) confers that minor benefit upon the creature's own natural weapons.

Here's a link to the D20 Hypertext SRD's entry on Damage Reduction, for a more complete description.

Also note that DR does not stack, rather the creature uses the best DR option for the situation.

There's an important distinction here between whether the DR is listed as, for instance "magic AND silver" or "magic OR silver". The creature with the "or" is at the mercy of his attacker in determining which applies, but at least gets some DR against anyone trying it with neither.

An example currently foremost in my mind is how demons rank up their DR - near the bottom of the scale the insidious Quasit calls DR on cold iron or good - so either a good-aligned weapon, or one made of cold iron will soon lay him low.

His boss, on the other hand, let's call him a Balor (extreme example but meh) calls DR against cold iron AND good - time to dust off the Holy Cold Iron Greatsword methinks.

I thought dvvega was just referring to those (rare) occasions like when an astral deva would be wearing adamantine full plate.

Only damage reduction/magic and damage reduction/epic work like that. Damage reduction/silver does not allow your natural attacks to overcome damage reduction/silver.

Nice, theres something to learn, wonder why I mistaked it would work on all like that.
