spikevampire 07-11-07, 06:36 AM	If i am a lv 10 champion of gwigijwstraft (book of exalted deeds, sorry but i hate this name) and i have 5 / - damage reduction, if i have an adamantine armor that give 3 / - thoose effect stack? i think so because armor is the same reduction of the "skin" reduction such as armor bonus and natural armor... i hope i don't mistaking... hi all
runestar 07-11-07, 06:42 AM	As a general rule, dr typically does not stack unless clearly stated otherwise. So the dr from your armour would not stack with the dr from your prc - you simply take the higher of the 2.
Leilond 07-11-07, 06:48 AM	DR never stack unless otherwise stated This means that it is totally unusefull an adamantine armour for a barbarian
Androcus Divinicus 07-11-07, 06:53 AM	Runestar and Leilond are correct. DR does not stack. You simply have a case where your class ability superceeds your armor's ability. Let me run a quick check of my rules to provide references. Regards, Justin. ::Edit:: References: DMG p. 292 "If a creature has damage reduction from more than one source, the two forms of damage reduction do not stack. Instead the creature gets the benefit of the best damage reduction in a given situation." I thought perhaps you might have a possible benefit if you were ever in an Antimagic Field, but the Damage Reduction given by the Champion of Gwynharwyf PrC is an extraordinary ability (BoED p. 57), and Antimagic Field only supresses Spell-like and Supernatural abilities (PHB p. 200). Finally, the DR granted by the Champion of Gwynharwyf PrC states that "a champion of Gwynharwyf gains the ability to shurg off some amount of injury from each blow or attack." This is more in line with the "rolling with the punches" view of DR as is the case with the Barbarian class upon which the Champion of Gwynharwyf builds. It is not in line with the "thick skin" view of DR as is provided by the exceptionally strong metal of Adamantine. Therefore your argument that "armor is the same reduction of the "skin" reduction such as armor bonus and natural armor" is unfounded in this case. It is possible, depending upon the level of your DMs experience, that you might be able to argue that since the Champion gains his DR from "shrugging off blows" and that adamantine gives you DR from just being really hard that they are, in a sense, "different bonus types", and they should logically stack, just like a Dex bonus stacks with a Natural Armor bonus when determining AC. Personally, I'd never let you get away with this, but your DM may be swayed. Also, you may be able to successfully argue that the DR you get from your Barbarian class levels should stack with the DR you get from your Champion of Gwynharwyf levels, similar to the way that if you're multi-classed into two different classes that both grant the evasion ability, you get improved evasion instead. Good luck. J.
spikevampire 07-11-07, 07:54 AM	i understand thanks a lot to everyone
runestar 07-11-07, 09:58 AM	The idea of dr not stacking was more to avoid possible abusive stacking, which is why it may not necessarily make sense from time to time (especially when multiple sources of dr accrue due to differing reasons). In the case, it would be more of a game-balance issue than a logical one.:)
spikevampire 07-11-07, 06:35 PM	yes i found it more balanced witouth stack but i would ask it just in case... :D
Yue Ryong 07-13-07, 11:15 PM	This is odd. I was sure that I saw somewhere that DR did not stack, with the sole exception of DR/-, which did stack. However, upon close examination of all the relevant entries in the core books, this does not seem to be the case. As I have actually given out advice on the basis of this poor information in the past, I now feel the need to apologise to everyone that I (unknowingly) misled. Despite the fact that I'm almost certain none of those people will ever see this. >_<
spikevampire 07-14-07, 09:12 AM	:) ;) :mad: :embarrass please found that rule!!!! :D :weep: :confused: :eek: :cool:
Neutronium_Dragon 07-14-07, 10:07 PM	DR/- doesn't inherently stack. There are abilities and feats which improve your DR/-, but that's a case of changing the single DR value, not stacking it with another one.
runestar 07-14-07, 11:00 PM	I think there are some prcs which state that the dr/- they grant stack with any previous sources of dr/- the PC might possess(runescarred berserker from UE?)
