Fast Study and Fox's Cunning


Rules Questions


In this example a Wizard casts Fox's Cunning, intelligence is high enough to grant at least another bonus spell.
First of all, would he gain another spell slot?

Can he use fast study to fill it with a spell?

1 minute is the minimum, 15 the maximum. Is there some fractional algebra to be done to calculate how long it would take to fill in the newly created slots?


Yes & yes, though they'd also need to cast it before the fox's cunning runs out I think.

As far as I can tell the time to prepare spells is just the number of spells prepared divided by the total number they could prepare. The level of the spells involved is not mentioned, but I'd leave out cantrips as not-really-spells.

A 5th level specialist wizard with 16 Int who pumps it to 20 with the spell gains 1 first level slot. They can prepare 5 first, 4 2nd and 3 3rd level spells normally, so it takes them 1/(5+4+3+1) = 1/13 the usual time to prepare just that one first level spell. If the usual time is 15 minutes then it takes them 15/13 = ~1.15 minutes. I'd usually round that to one minute.


Fox's Cunning would NOT give an extra spell slot. Bonuses have to last more than 24 hours (like from a Headband you wear that long) before they Effect spell slots.


So I guess the same is true for School abilities that give 3 + INT modifier.

What if the ability to use such a school abilities were also only "borrowed", for example through Paragon surge as an arcanist, picking up School understanding (based on charisma).

So in this example the arcanist with 14 charisma, would cast eagle's splendor and then paragon surge to pick up school understanding.
Would have 5 uses or 7?

Let's say he uses 3 of these powers. Later on he casts paragon surge again (without eagles splendor).

Would he now have 2 or 5 uses?


Yes, anything that's usage-per-day needs to be permanent bonuses. Temporary bonuses like Fox's Cunning do not give additional uses of school abilities. Paragon Surge is a weird effect, but it doesn't change anything here. Eagle's Splendor is still a temporary bonus and temporary bonuses do not increase your uses per day of abilities.

Temporary Ability Score Increases vs. Permanent Ability Score Increases: Why do temporary bonuses only apply to some things?

Temporary ability bonuses should apply to anything relating to that ability score, just as permanent ability score bonuses do. The section in the glossary was very tight on space and it was not possible to list every single ability score-related game effect that an ability score bones would affect.

The purpose of the temporary ability score ruling is to make it so you don't have to rebuild your character every time you get a bull's strength or similar spell; it just summarizes the most common game effects relative to that ability score.

For example, most of the time when you get bull's strength, you're using it for combat, so the glossary mentions Strength-based skill checks, melee attack rolls, Strength-based weapon damage rolls, CMB, and CMD. It doesn't call out melee attack rolls that use Dex instead of Str (such as when using Weapon Finesse) or situations where your applied Str bonus should be halved or multiplied (such as whith off-hand or two-handed weapons). You're usually not using the spell for a 1 min./level increase in your carrying capacity, so that isn't mentioned there, but the bonus should still apply to that, as well as to Strength checks to break down doors.

Think of it in the same way that a simple template has "quick rules" and "rebuild rules;" they're supposed to create monsters which are roughly equivalent in terms of stats, but the quick rules are a short cut that misses some details compared to using the rebuild rules. Likewise, the temporary ability score rule is intended as a short cut to speed up gameplay, not as the most precise way of applying the bonus.

A temporary ability score bonus should affect all of the same stats and rolls that a permanent ability score bonus does.

Temporarily gaining abilities: If I temporarily gain an ability that is limited in its uses per day, am I limited in my overall uses of that ability if I can temporarily gain it more than once?

Yes. You are limited by the ability in the same way as a character that has that ability permanently. For example, if you have an ability that allows you to gain the Stunning Fist feat for a limited period of time and you use it 3 times. Those uses count against your total number of uses should you temporarily gain Stunning Fist again later that day. This limit also applies to abilities that grant additional uses of another ability (such as Extra Channel). Once used, they are consumed for the day, even if you gain the ability again.


@avr
So it does work? Neat. Pretty awesome for spontaneous spell casters, pretty good for Arcanist class feature consume spells.

So unto that last point. When you use Eagle's Splendor and get extra uses of School Understanding, once it the CHA bonus resets is it assumed that your initial uses of that ability are off the temporary CHA bonus or does it sort of retroactively take them from your regular uses?

If it did that, isn't there some implication that since you're at 0 (rather than negative 2) once you recast Eagle's Splendor you should have 2 uses again?


That second FAQ says recasting Eagle's Splendor or similar the same day 'remembers' if you've used the bonus uses and stops you using them again. If you've used your base uses only and haven't touched those gained via ES, fine - recasting brings those bonus uses back again.

I'm not sure whether uses of school understanding would come off the bonus uses or base uses first, sorry.


That FAQ refers to bonuses, not uses per day of abilities. This is the only remaining distinction between permanent and temporary bonuses in light of that FAQ. I have never heard of anyone claiming that this FAQ allows you to gain additional ability uses per day, and this would represent a radical break from convention.

The second FAQ is in reference to abilities like the Paragon Surge spell or Martial Flexibility, which allow you to spontaneously gain other abilities that may be limited in usage per day. If you gain the same ability again later in the day, the number of uses from earlier is "remembered". This does not refer to using Eagle's Splendor or the like to gain additional uses of a daily ability.

The closest equivalent to using temporary ability bonuses to gain additional ability usage would be temporary bonuses to constitution and how they apply to hit points. Temporary constitution bonuses add temporary hit points when gained and then remove those hit points when lost, potentially killing you by dropping your hit point total negative. So if you want to go with this, casting Eagle's Splendor would give you +2 ability uses, but then when the duration ended you'd lose 2 ability uses. This could potentially drop your ability usage per day into the negatives.

The Exchange

I started with "What, no way this works", to it works with somethings. Than reading these FAQs, I'm not so sure. Look at it from the brand new player veiw. Throw out all you have ever learned and done it, and the OPs question dosnt sound so crazy anymore. Or my 2 hours sleep deprived mind needs to rest more.
No offense meant. I am rethinking things now. It opens up a lot of weird game play. Even if does work, it can only do so "once", because you couldnt creat another empty slot by casting fox's cunninng

The Exchange

As for times per day, would work like temp HP. Increase both gained and total, but lose both too. So more an end of day, after spending all your normal uses kind of thing.


Now, assuming a cleric doesn't have a headband of alluring charisma because he's wearing a phylactery of positive channeling, and he's exhausted his uses for the day, would a mere casting of eagle's splendor grant him 2 more uses of his channel positive energy?

Specifically stated in the Fox's Cunning description:

Wizards (and other spellcasters who rely on Intelligence) affected by this spell do not gain any additional bonus spells for the increased Intelligence, but the save DCs for spells they cast while under this spell's effect do increase.

It doesn't call out specifically any other abilities that are used a number of times per day, but based on that I have always assumed it doesn't give you extra times per day.


Eagle Splendor wrote:
The transmuted creature becomes more poised, articulate, and personally forceful. The spell grants a +4 enhancement bonus to Charisma, adding the usual benefits to Charisma-based skill checks and other uses of the Charisma modifier. Bards, paladins, and sorcerers (and other spellcasters who rely on Charisma) affected by this spell do not gain any additional bonus spells for the increased Charisma, but the save DCs for spells they cast while under this spell's effect do increase.

So, would a cleric's DC for channel positive energy which is based on charisma (but isn't a spell) still increase? Then why wouldn't his uses per day 3 + Cha modifier?

The FAQ is still a little vague.
