When GMing a PFS table, what rules most often need to be explained or briefly revisited to make sure everyone is on the same page? I'm not talking about Table Variation, but the normal PF/PFS rules.

Examples:

The Grappled condition...what can and can't I do?

Readying an action--you can't ready an action outside of combat and you can't ready a full-round action (and, sometimes, the initiative consequences of a readied action triggering in the next round)

Owning Herolab/consulting a website does not equal owning the material

etc

  • What (and when) you can and cannot take 20 on.
  • Kn:Arcana to identify auras (Conjuration, Illusion, etc) vs. Spellcraft to identify abilities of items/spells.
  • ITS use and need

    How the "Heal" skill works.


    How many attacks of opportunity we get, and whether or not an action "should be possible". We have a physicist in our party, so things get...complicated. And hilarious.

    I always have to explain how bonuses from cover are applied. I have players who continually try to take -4 from their attack rolls, when I try to point out that it's actually a +4 bonus to the defender's AC. Mathematically, it's the same effect on the die roll, but it is mechanically different.


    My campaign is full of new players (myself included), so we get a lot of recurring questions that would make experienced players shake their heads.

    Reach weapons and cover.

    The difference between readying and delaying, and more importantly, why you would choose one over the other.

    Combat pets are not an extension of your character, so they can't a)automatically know what you want them to do, b) see and know everything you do, c) have the ability to accomplish complex tactical maneuvers (like "ready an action to attack the wizard if he starts casting"--I only allow that if the player also readies an action to command the pet). This varies from pet to pet, of course, but there's a tendency (a fairly natural one, I think) for players to treat their combat pets as telepathically linked clones of themselves.

    Less an actual rule misunderstanding, but I often have to remind players of the bonus types (and that same type bonuses don't stack).

    Charging an enemy with reach. Does it provoke an attack of opportunity.

    One part of the rulebook says yes, as you are moving through a threatened area. Another part says no as you are charging and the charge action does not.

    I really wish there was an official FAQ on this one instead of digging around forum posts by non-rule writers.

    That ones easy. You'll provoke if you move through the space, but not for the act of charging itself. Same as flying does not make you immune to being flat footed just because the chart says you're not flat footed just because you're flying

    Silver Crusade 1/5

    And if we start listing rules everybody disagrees on in dire need of a FAQ we'd be here all day.
    Jump DCs, are they for jumping over a x-foot-gap or do you have to jump from square to square like a broken knight? That is, do you need to hit a 5 or a 10 to jump over one square?
    Using Acrobatics to avoid attacks of Opportunity, do you have to declare your whole move a tumbling action or can you choose to only tumble on certain squares (so these are the only ones where your speed is halved) and if it's the former, how does this interact with double moves?
    A paladin's detect evil, is it always the move-action-version described or can he choose between the standard action and the move action version or does he have to activate the normal version before using the move action version? (Though this is slightly easier to solve than the others - the move action version would be completly idiotic if he really had to spend a standard action to keep it up every round as the spell does, so it's probably not the third version.)

    And so on, and so on...

    EDIT: Okay, maybe not everybody disagrees on, some of them seem to have a consensus. But there are always enough people arguing for the other side because it's vague enough.

    Dark Archive 4/5 5/5 ****


    • Moving through threatened squares of multiple enemies. (one roll, or many. Where to the penalties apply?)
    • Spell penetration -- is it (1)caster level + feats/etc., or (2)caster level + casting stat bonus + feats (for the record, it is (1)
    • Swarms

    2/5

    Additional Resouces and needing to own the books outside the Core Rulebook if one wants to use something.

    When one can Take 10 or Take 20. Lots of people not letting me take 10 to swim in not-so-calm water, or climb rope, or jump a pit, escape bonds, or pick a lock outside of combat because of the "risk of negative consequences when failing" rather than caring about the "not in immediate danger or distracted" part of taking 10. Folks keep mixing up the Take 20's "When you have plenty of time, you are faced with no threats or distractions, and the skill being attempted carries no penalties for failure" requirements for Take 10.

    Precise Shot and careful positioning for ranged attacks are important if one doesn't want buttload of penalties for the shot. Ranged combat is pretty strong as lot as those things are watched out for. Shooting into Melee is -4 to the attack. Cover grants the bonus to AC, not extra penalties to the attack. Cover is something the GM is supposed to be in charge of when determining if an attack hits, not an extra penalty to be thrown at the player.

    Even though everyone is aware of each other and itching for a fight, once initiative is rolled, and someone hasn't acted yet, they are flat-footed. If someone initiated the fight by throwing a punch, that may be a surprise round, but if they roll low on overall initiative, folks are gonna recover mighty quick.

    Readying an action does change the initiative order. If someone's readied action gets triggered, in subsequent rounds, his new initiative order is right before the target who triggered the readied action.

    Spellbooks and Learning New Spells.
    Every time someone starts up playing a wizard/magus/alchemist for the first time in PFS, I gotta check how they've been adding extra spells to their spellbooks. More often than not, they've been buying scrolls and scribing the spells from that. Those players get confused/surprised when I gotta pull up the magic chapter and the scribing/spell obtaining costs are a fraction of what they're paying.

    Silver Crusade 3/5

    Here are some:

  • That I can take 20 on Perception to search for traps ("Yes, I know I didn't find anything at first glance, I'm going to look again.")
  • That taking 20 on Perception takes one minute, not twenty minutes.
  • That I can take 10 to Climb.
  • That a creature with Combat Reflexes can still only take one attack of opportunity against me for moving through its threatened area, regardless of how many threatened squares I move through.
  • That activating a pearl of power (or any other command word activation item) requires a standard action (unless otherwise noted in the item description).
  • That encumbrance is not hand-waved away in PFS.
  • That line effects must originate from your square.
  • That firing ranged touch spells into combat carries with it all the same penalties that all other ranged attacks carry.
  • That Bob's ability which lasts 1 round expires at the beginning of his next turn. (I'm looking at you, Bit of Luck (Su).)
  • That the Sword of Valor paladin archetype ability to add Cha to Initiative does not stack with the Noble Scion (War) feat, despite being shown the FAQ. (In fact, they claim that the FAQ specifically allows it.)
  • That arcanists can cast sorcerer/wizard spells found in sources other than the Core Rulebook.

    Since the rule you cite is referring to the entire Skills system as a whole, "usually" means "for most, but not all, skills". That means you need to be able to name at least one "skill that takes 1 round or less to perform" for which "usually 2 minutes" is NOT the case.

    If Perception doesn't fit the bill, then which skill does? Because if you can't name a skill that takes 1 round or less to perform and does NOT take 2 minutes to T20 on, then you end up changing "usually" to "always", which is by definition against the rules.

    But if someone wants to stick to the assertion that T20 always takes at least 2 minutes no matter what, then I guess I can just say "In that case, instead of 'taking 20', I'll just spend 20 move actions to roll 20d20" and throw a bunch of dice on the table, then tell you the highest result. And that will take me 1 minute, with no wiggle room to argue otherwise.

    I should note that if I get the time to take 20 for searching for traps down to two minutes, I let it go at that point. It is such an improvement over "Okay you can take 20 but that will take 20 minutes."

    PRD wrote:
    Combat Reflexes and Additional Attacks of Opportunity: If you have the Combat Reflexes feat, you can add your Dexterity bonus to the number of attacks of opportunity you can make in a round. This feat does not let you make more than one attack for a given opportunity, but if the same opponent provokes two attacks of opportunity from you, you could make two separate attacks of opportunity (since each one represents a different opportunity). Moving out of more than one square threatened by the same opponent in the same round doesn't count as more than one opportunity for that opponent. All these attacks are at your full normal attack bonus.

    True.

    Yes! Pathfinder math, where the shortest path can actually end up in 3 different squares thanks to the first 5' diagonal only being 5'

    E.G. you have a huge monster 4 squares from a PC as seen below with X and numbers being empty squares, O being the monster, and P being the PC:

    X X X X X
    X o O o X
    X o O o X
    X o O o X
    X 1 2 3 X
    X X X X X
    X X X X X
    X X P X X

    Technically any one of 1, 2, or 3 are mathematically the closest distance to charge and are all straight lines, thus any of them are legal to charge to. I've seen plenty of people that disagree with me, but haven't found anything in the rules that would deny it.

    For those of you who are curious, in Golarion π = 4. But there is no general formula for the area of a circle like A = π r² like there is in our world.

    I have this issue but in reverse. I've only been playing a few months, but none of the 6 GMs I've played with allowed me to pay an NPC for spellbook access. They say this isn't allowed in PFS and that you have only two ways to get additional spells: 1. buy scrolls 2. copy from the spellbook of another PC who is running in the same adventure as you.

    The last GM said that he had a 12th level wizard and had never heard of being allowed to pay an NPC for spellbook access.

    Then there was the GM that said I couldn't take 10 when learning a spell from a scroll. Having to buy a new scroll for each failure gets expensive real fast.

    In this area it's common to need to be informed of stacking rules on various things. Types of bonuses mostly.

    We've had lots of back and forth discussions over falling rules when you are greater than 400 feet or whatever in the air. To be precise 5000 feet. We ended up using the rules of real world physics for that one.

    How magi work. Just in general. Spellstrike is apparently complex for some people. As is spell combat.

    No, I don't. I disagree with your assertion that the rule means "for most, but not all, skills"

    I think it means most of the time, all skills that are 1 round or less to use take 2 minutes to take 20.

    As a GM I'm sure there are some circumstances where I think 1 minute would be appropriate for take 20 on perception. However I've found "searching x" to be by far the most common use of take 20 and think it obviously fits into the usually box.

    I'm happy to disagree rather than argue further on what is really just rules minutia though.

    I'd argue that as soon as you have to take a diagonal step you are covering a greater distance than by running a straight line because while it only counts as one square, this is not because the distance is the same but because it's the only way how diagonal movements works in a square-based environment. By running the same path twice positions 1 and 3 were suddenly 7 squares while position 2 was 6 squares. And we all now:

    x*2 = 7, y*2 = 6, thus
    x*2 > y*2 --> x > y.
    So the way to positions 1 and 3 should be longer.

    Just because the first diagonal only counts as 5' that does not mean it actually IS 5'.
