[ That is how you would do a skillcheck roll yes, for skill checks, attacks, more or less anything save for damage, concealment and a few others, you roll a d20 and add all of your modifiers for the appropriate action. The only thing I might suggest, is to break down the information for your modifier so instead of 1d20+10, it would be 1d20+ 10(+5 ranks, +5 intelligence) something like that so that it is easy to understand how you came to the +10, it can help you to better learn the system, and makes it easier for others to help and point out things you may have forgotten to include be they helpful or otherwise.....just my 2 cents on the matter :3 ]<br/><br/><br/>[A thought I had on Anal vore in particular, while I agree it should be functionally the same as oral, I would suggest it perhaps having a few more steps, i.e. take longer. So as where normal vore goes (grapple---> mouth---> stomach) anal would go something like, (grapple---> ass---> large intestine----> small intestine----> stomach) Though could potentially benefit from a circumstance bonus making it harder to escape from due to the increased tightness. If you wanted to make it even more complex and different it could for instance be harder to initiate,(as it would likely be more challenging to perform vs a unwilling participant then simply nomming then via conventional means) meaning there is a penalty for the pred when going from the grapple to ass stage, but once the prey is inside, it would be more difficult for the prey to escape as i mentioned earlier. Of course once the prey was in the stomach they could then opt to escape via the throat.....which brings me to a question, what happens ,if anything, if say a prey successfully escapes a predator's stomach, and moves back to their mouth, while the pred already has another prey in their mouth? Would they be unable to escape, or would say the prey in the mouth be forced out?..............just a few musings I had on the subject, by no means do they have to be implemented :3 ]
