The instructions do tell you to add the obstruction. Well, the obstruction includes the walls, after all, why are they shown if they aren't part of the obstruction? You can't have it both ways. You say there's nothing about adding the walls. There's nothing said about not adding the walls. The diagram is all we have and the diagram clearly shows where there are walls and where there aren't walls. It's not as if the obstacle is in a simple box, the obstacle is shown with detailed walls and gaps. Those gaps must mean something otherwise why are they there? This particular problem has been removed with the Mapping Game. This shows you acknowledged the walls do not (or should not) belong to the obstacle. All I'm suggesting is the core rulebook reflects this change. As for the grayness of the walls shown in Table G. My reply to that is you shouldn't assume colour to begin with. Page 26 tells us that areas can be marked with a Y, R, G, or B. The grey walls are just acknowledges that colour (or letter abbreviation) doesn't change due to the obstacle.

That answers my question. Thanks. I really don't see how this conclusion can be arrived at just reading the core rulebook. That suggests either both exits past the bridge are present or neither of them are. Table G - Geographic really needs to be errata'ed as entries such as G18, G30, G41,G44, G49, G51, G59, and G65 are wrong (at least the diagrams are incorrect). The Mapping Game components give a better idea how these tiles are meant to be implemented but that requires the Mapping Game to have been purchased, even then the Mapping game doesn't explain how you deal with G49 or G51 in full. Not everyone who plays D100 Dungeons have access to the Mapping Game.

There appears to be a misunderstanding here. I'm using the core rulebook. I rolled 39 on Table M - Mapping.I rolled 30 on Table G - Geographic. This shows a straight through corridor with a door at the far end. This shows a right hand corner with an exit to the right. What do I draw? G30 blocks the door exit and M39 blocks the right hand opening. For example, which is correct? No exits or a Door and an exit?

No it doesn't. The Mapping Game instructions does not tell you what you are meant to do with a door. The Map Tile shows a door, the Geographic tile does not. The Mapping Game doesn't tell you at all what to do with the door at all. How is this situation resolved if I'm not playing the Mapping Game? How are people who do not own the Mapping Game meant to resolve this ambiguity?

I recently purchased the hardback d100 Dungeon books, they arrived just over a week ago and so in addition (or celebration :) ), I purchased the Print and Play Mapping Game. The cost of the physical copy was way too high for my tastes plus the shipping to the UK is expensive. I've just finished laminating and cutting out all the components, they look very nice indeed. I'm somewhat disappointed the PnP didn't include "all" the actual components such it could mirror the original. All that's really needed are the tokens and the 4 missing Map tiles (you don't need duplicate Monster cards). I can see why these components were not included in the GameCrafter physical release, and I think it was simply due to cost. For example, only 96 of the 100 Map cards are included and it may be the card punch used to make the Map tiles produces 12 at a time. Instead of having 8 surplus cards each batch it was cheaper to just make 96 and not a 100 of them. Same with the tokens, there really should be 100 Door tokens, 100 Encounter tokens and a 100 Geographical tokens. It seems rather short sighted not to offer these as well (if not in the physical game, then at least in the PnP). I can't see any reason why the missing tokens were not included in the PnP. So, to answer your question, I would suggest cost was the main reason. There are other possibilities but I hope it was only due to cost and not any other reason. As you mention the Encounter odds for low level encounters are seriously off. On a non adjusted Encounter roll, there is 10 times more chance of encounters a DRAGON / WYRM than a Giant Rat!!! That is so wrong on so many counts. My solution is to now create all the missing Door, Encounter, and Geographical tokens, that way I can use the Mapping Game and have a "proper" game of d100 Dungeons :) While I'm at it, I'll create the four missing Map Tiles.

Based on what pages 6 and 7 say in the LToER, I would say a purchased Beast is tamed. Page 6 "If they tame or buy another, the old one will wander off and be lost forever." Page 7 "When they are bought or tamed, its level begins at (1). If it wasn't already tamed when you purchase it, it wouldn't need to distinguish between being tame or being brought. It would say "If another is obtained, the old one will wander off" or "When tamed, its level begins at (1)."

A Monster's DEF is very different to the Adventurer's DEF. It was a poor choice to abbreviate both to DEF. A Monster's DEF acts the same way as Armour does for the Adventurer. If a Monster has a DEF of 2, then 2 is always deducted from the damage. An Adventurer's Defence Bonus is a bonus that might or might not apply. This bonus only applies when the Monster's (natural) damage roll is equal or lower than the Adventurer's DEF value. There is one exception to this, and that is if a natural 6 rolled for the Monster's damage, in which case the Adventurer doesn't get the opportunity to apply their Defence Bonus. So, a Monster's roll of a natural 6 means your Adventurer can't apply their Defence Bonus. Your Adventurer still applies their Armour and can apply Damage Deflection (if applicable). The Monster's DEF always works no matter what the Damage dice roll was. It's effectively the same as Armour (in terms of game mechanics). Hope that helps.

@Martin Knight Could you confirm that the number is in fact truncated. Thanks. This appears to be treated differently to when shading in Damage Deflection since there a Shield can have 0.5 pips shaded.

Indeed, you can stack the fractional DEF bonuses, the example Adventure Sheet on page 16 does exactly that. The issue isn't if you can stack them or not (and there's no reason to think you can't stack them), the question is what to do with the factional part of such a DEF bonus? I can imagine most people will just round the number but some might round 1.8 up to 2. Rules as written, it suggests you should simply apply fractional HP as the rules tell you to subtract the DEF, so if you have a DEF of 1.8 you should therefore subtract 1.8, not 1 (or even 2).

Many thanks Martin, that certainly helps. When you say "The modifier remains until it is replaced" does this mean it can span several days (if a Quest lasts more than 12 hours for example). Can this modifier span several Quests? I can't see anything that tells you to erase the modifier (except on page 28 where it implies it only can be replaced but not erased). On page 29 (Before Your Next Quest - Refresh Tracks) it doesn't mention erasing this part of the Time Track. I must admit, I would have never guessed the correct answer to this (specially the -1 DMG). I still don't see any guidance in the existing rules which point me to this answer. Similarly, I don't see any real hint how to handle any of the Time Track Modifiers in the existing rules. Clearly, you know the answer, but the rulebook is silent on how it should be resolved. Now you've explained it, the intent is mostly clear (except for how long the modifier lasts), but without your explanation it didn't make any sense to me.
