creatures and ride by attacks

By the 8 spider, in Dark Heresy Rules Questions

i find diffcult to calculate how much a creature deal natural damage because natural attacks can greatly change. the core book has a entry for a beast of burden. well i think it 's especialy light and i'am expecting a book about creatures. beast of burden? a horse is a beast of burden like a cow but i think that on some world a cold blood or any saurian can be described as a beast of burden and when you compare a cow to a cold blood then the template beast of burden can't work.

- does any one as idea about what caracteristic a cold blood could have because i am working on a campaign on a exodites world where human are the only mamals.

- same question for giant spider like the one describe in necromunda and that can serves as mount.

- i don't find a rule for fighting in melée or shooting while riding a mount or for riding a war mount. does it exists?

I realize English is not your first language, so I'm sorry if I talk over your head. I'm also sorry if it sounds like I'm speaking condescendingly to you. Neither of those things is my intention.

A cold blooded creature could be simulated by forcing it to suffer fatigue in cold environments or whenever it takes damage from cold. If it runs out of fatigue in this way, it dies. Some will be better tolerant of cold than others - you should figure out the details. Also, if you're recreating a creature from another source (like Necromunda), lean on that some and fill in the blanks for the rest.

Vehicle and mounted combat rules currently only exist in Apocrypha: Vehicles . That was a PDF published for free by Black Industries as an "unofficial rules supplement" until and unless better rules get published later. I don't think FFG has been hosting it, but you can find it elsewhere.

don't worry i know that english is not my native tongue . i'm working to improve it. when i talk about cold blood i in fact talk about the creature that's de druchii of warhamer name nauglir.

I think the "Dustdogs" from the core rulebook adventure "Illumination" should suit your needs (a bipedal, predatory reading beast like an oversized raptore lizard) quiet fine. :)

thank for the idea but it doesn't suit me so well. cold blood should have other "qualities" like stipidity and maybe a better natural armor.

i was wondering how could work a ridding skill and to wich attributes it will be link.

but definetly it will help that some creature could be describes as riding beast or can be use with a vehicule. the xenos systeme generation doesn't have this describtion. i am wating my exemplary of creatures anathema. but in the mean time can some of you tell me if there are creatures in this book that are describe as possible mount including flyer?
