A few questions related to AC.


Rules Questions


Now I have only ever played one RPG, and that was Rifts. I have gotten some what tired of having to own 50+ books to play a fun game, so i decided to pick this up after a great conversation with a Fellow GM at a Comic book store.
My question comes from understand more difficult rules from the Rifts System. Does AC effect the the chance to be hit, or to do damage. Does a high enough roll but not the total AC rating mean you hit but do no damage do to armor? or does AC work like a Active Defensive system, where a fail roll means no hit, The PC naturally parried or dodged the attack or even take the the hit but AC prevents any damage.
Or am I making a Fun easy System harder than it needs to be lol.
Also is there a Targeting system, as in a way to Shoot a hand, or head.


I think you're complicating things. AC is an abstraction, representing both the chance to avoid a blow as well as the chance that it's absorbed by armor, a shield, etc.

As far as a "targeting system", there's a variant rule for Called Shots which sounds like what you're describing.


I just want a better AC system Period


As Oladon mentioned, it's a simplified abstraction because it technically does include things like actively dodging incoming blows (DEX bonus to AC) as well as deflection of attacks by armor (armor AC) or blocking attacks with a shield (shield AC).

Fluff aside, per the PRD, AC is "...the attack roll result that an opponent needs to achieve to hit you." If the aggressor's attack roll, with all valid bonuses, does not meet or exceed the the target's AC, then the attack does not hit in any way that allows any effect beneficial to the attacker to trigger.

As for the variant 'called shots' rules, you can read about them on the Pathfinder Resource Document here.


I'm not sure the Rules Question forum is the right place for this.

As Oladon said, AC is an abstraction that only has meaning inside the meta-level of the rules. What exactly happens when an attack fails to beat the AC is completely up to GM and player. Just as it is up to them to decide what HP damage means. One could, for example, say that most "hits" don't really wound someone, with the first hits just wearing them down until the latter strikes actually break the skin and the last pierces his hearth.
All up to the GM.


I thought/figured i was making the AC system more difficult then it needed to be. I have not run a game yet, I may run a few small task with my Players till we get the hang of this new system before I pick up the pace.
I was hoping their was no Called shot system.

Most of the groups with which I've played don't use Called Shots. Like I said, it's a variant rule, which means it's completely up to your group whether you want to use it or not.

Have you considered running something from the Beginner Box?


Ahh, sorry. I will better try find the proper location for my questions.


Not yet, I honestly only got the PDF core, hardcover core, and PDF beast. Figured with the hyperlinks in the PDF it would make for faster game play in the beginning.


Check out this page. There are a bunch of free resources at the bottom that you'll probably find quite useful, especially if you don't intend to start with the Beginner Box.

And always feel free to ask your questions on the forums. The Advice subforum is a great place for them!


It's ok, as I'm said I'm not sure if it is the right subforum. After all you were of the impression that this is part of the rules (in which case this forum would be right), even though it isn't (which would make the rules forum the wrong place).


All new to this Message board, will have to sort through all of its to better suit my question location. Also replying to everything so I can save to my name lol


Awesome , Thank you Oladon
