Preparing Wizard spells multiple times in day


Rules Questions


Wizard spells:
/.../

A wizard can cast only a certain number of spells of each spell level per day. His base daily spell allotment is given on Table: Wizard. In addition, he receives bonus spells per day if he has a high Intelligence score (see Table: Ability Modifiers and Bonus Spells).

A wizard may know any number of spells. He must choose and prepare his spells ahead of time by getting 8 hours of sleep and spending 1 hour studying his spellbook. While studying, the wizard decides which spells to prepare.

Preparing Wizard Spells:
Rest: To prepare his daily spells, a wizard must first sleep for 8 hours. The wizard does not have to slumber for every minute of the time, but he must refrain from movement, combat, spellcasting, skill use, conversation, or any other fairly demanding physical or mental task during the rest period. If his rest is interrupted, each interruption adds 1 hour to the total amount of time he has to rest in order to clear his mind, and he must have at least 1 hour of uninterrupted rest immediately prior to preparing his spells. If the character does not need to sleep for some reason, he still must have 8 hours of restful calm before preparing any spells.

Recent Casting Limit/Rest Interruptions: If a wizard has cast spells recently, the drain on his resources reduces his capacity to prepare new spells. When he prepares spells for the coming day, all the spells he has cast within the last 8 hours count against his daily limit.

/.../

Spell Selection and Preparation: Until he prepares spells from his spellbook, the only spells a wizard has available to cast are the ones that he already had prepared from the previous day and has not yet used. During the study period, he chooses which spells to prepare. If a wizard already has spells prepared (from the previous day) that he has not cast, she can abandon some or all of them to make room for new spells.

When preparing spells for the day, a wizard can leave some of these spell slots open. Later during that day, he can repeat the preparation process as often as he likes, time and circumstances permitting. During these extra sessions of preparation, the wizard can fill these unused spell slots. He cannot, however, abandon a previously prepared spell to replace it with another one or fill a slot that is empty because he has cast a spell in the meantime. That sort of preparation requires a mind fresh from rest. Like the first session of the day, this preparation takes at least 15 minutes, and it takes longer if the wizard prepares more than one-quarter of his spells.

Straight to the point. Can you prepare spells multiple times in a day?

I know that you have a daily allotment of spells, so a Wizard couldn't get more spell slots no matter how many times they prepare over the course of a day. I am more curious about if I can decide to take a 8 hour rest in the afternoon to abandon the spells I prepared in the morning, and replace them with others. This wouldn't break any daily allotment limit, and the rules for preparation does say that "a mind fresh from rest" is the one requirement to abandon/replace prepared spells.

I do know about the Ring of Sustenance which doesn't allow you to prepare spells multiple times, but I figured that was a limitation specific to the ring.

No. All prepared spellcaster can leave empty slots and spend time preparing spells in them later in the day, but you need specific abilities to abandons and replace spells after the daily rest. Oversleeping doesn't change that.

That's an interesting idea, but the whole paragraph seems to be about spell slots left open.


I don't see why not.

A wizard who goes to bed at 10pm on day 1, wakes up at 6 am on day 2, spends an hour preparing spells, adventures for an hour, takes a sedative and sleeps from 8am to 4pm, then wakes up and spends an hour till 5pm preparing their spells again would seem to have fulfilled all of the requirements in the rules for preparing spells.

It seems like it would have been easy enough to stipulate that you can only go through a full preparation once every 24 hours, as is the case, implicitly, for divine casters, if true "once per day" preparation had been the intent.

Well they are daily spells, and you have a list of spells per day.

Technically if you're on another planet/plane/etc with shorter days you could, though with that logic you'd have to be really careful on Venus where a day lasts ~5,800 hours.

Sure, and that's a nice shorthand for the class feature, but the actual rules for preparing spells don't really care about "days".

The daily limit is actually an 8 hour limit.

EDIT: Mea Culpa, I got a little confused between preparation and spells per day. I'll maintain that a wizard could fully prepare spells multiple times per day, abandoning previously prepared spells and choosing new ones in their place, as outlined in the first post - but you're right to point out that they won't get new spells per day by doing that. It'd just be repurposing unused spell slots.

EDIT 2: Reading back through the rules again, the "(from the previous day)" clause under the "Spell Selection and Preparation" heading would seem to limit abandoning a prepared spell in an unused spell slot to once per day. Darn.

Yes, you can, there are rules & limits though. You can also prepare multiple identical spells.

> ... specialist wizards receive an additional spell slot of each spell level he can cast, from 1st on up. Each day, a wizard can prepare a spell from his specialty school in that slot. This spell must be in the wizard’s spellbook.

that is different, and No. You cannot normally replace memorized spells with other spells, see CRB RAW spoiler above.

8hrs rest doesn't make a difference except towards the next spell preparation. Filling empty slots takes 15-60 min.

I'll add that if a wizard rests, is up at 8am, memorizes all his spells by 9am, then rests 8 hrs - his adventuring day is over and it's 5pm.
Personally: By 6pm I'd let him memorize all spells (that haven't been cast) and reset his 'day' for memorization to 5pm in the evening. He's basically gone to night shift and lost half a day and the slots for previously cast spells. He can get those back the next evening.

There are feats to shorten this time; Quick Preparation, Spell Mastery.
Feat to prepare something different; Versatile Spontaneity.

Nope. It is a general rule for memorizing spells. The reiteration is there to head off confusion about memorizing spells as the ring lowers the required rest from 8hrs to 2hrs.

Spell Preparation Time: After resting, a wizard must study his spellbook to prepare any spells that day. If he wants to prepare all his spells, the process takes 1 hour. Preparing some smaller portion of his daily capacity takes a proportionally smaller amount of time, but always at least 15 minutes, the minimum time required to achieve the proper mental state.

"that day", not "till he rests again".

Drugging yourself unconscious isn't rest, it is drugging yourself.


It's not intended that you be able to prepare your full spell allotment more than once per day in PF (tho' it was the opposite in AD&D; can't remember for sure in 3.x), there's evidence in this thread from James Jacobs. As to whether the actual rules are nailed down hard enough to enforce that I leave you to the other posters.

3.x has always been once per 24 hour period. While AD&D did not limit you to "all slots once per day", you still had to be fully rested (which basically meant prepping after combat was out) and memorization took a lot longer than it does now - 15 minutes/spell level in 1e and 10 minutes /spell level in 2e.

Liberty's Edge

I just want to point out that while a lot of people are saying 24 hours a "day" on a particular planet may be more or less than that. Regardless of how many hours a day is you can only do it once.


I'm not fully convinced, but I'm obviously biased as I want it to work. So I shouldn't listen to myself.

Moving on

It should be possible to sleep 7 hours during the night, be "interrupted" for half a day, and then spend 2 hours resting to regain spell slots in the late afternoon. And the morning after that day regain spell slots as normal with 8 hours of rest.

Or does the first preparation of the day (which is what regains spell slots and allows you to abandon spells) have a 24 hour timer?

It has never clearly ruled if you can prepare spell only 24 hours after the last time you completed the previous preparation. I would say that there is some margin, otherwise you would end pushing the time forward every day, as it is almost impossible to start at the exact time, especially in a world without reliable clocks.

Fort the 7 hours, long interruption, 2 hours, I would say "normally not", as the long interruption would potentially tire you.
In a home game I could allow it with a home made trait.


To be fair, "daily" abilities are meant to refresh after any qualifying rest (8 hours) regardless of sleep, how much actual time has passed, the cycling of the sun/moon etc. Aside from the already mentioned issue of alternate planets/planes (including personal demiplanes with timey-whimey shenanigans), theres the issue of how do you handle wanting to adventure at night?

Do the casters just lose their spells at midnight? If not, what stops them from not having to fire their spells into the dirt to refresh them after a rest? The only exception I can think of to the "all daily abilities refresh every qualifying rest" is clerics and similar prepared divine casters that actually pray at a specific time of the day or they get nothing.

In either case, a spell slot is specifically called out as not being able to refresh after a rest if it was casted less than 8 hours ago. This of course overrides the concept of "daily" ability as something actually fixed to a 24 hour cycle.

Can you make some examples?

Especially for Arcane caster?

A Magus recovers the arcane pool when he prepares his spells (and that was very relevant while playing the second module of the Carrion Crown AP).
Some of the Wizard school abilities have a "per day" counter, some reset when you prepare the spells.
Most Witch hex can't target the same creature for 24 hours, so they are linked o the clock, not the "day".

Divine spellcasters generally have a "per day" limit of uses.

None has a "per rest" counter AFAIK. That is 5th ed. D&D.

BTW, that quote has a reply to the OP: "had spells prepared (from the previous day)". So you can abandon spells prepared the previous day. No mention of abandoning spells prepared today. As you already prepared spells today, all your spells have been prepared today, even if you sleep again in the day.


It comes from the magic rules directly and while it was only ever officially explained for the core casters, its easy to assume which matches closer to what and go from there:

Sorcerer and Bard wrote:

Daily Readying of Spells

Each day, sorcerers and bards must focus their minds on the task of casting their spells. A sorcerer or bard needs 8 hours of rest (just like a wizard), after which she spends 15 minutes concentrating. (A bard must sing, recite, or play an instrument of some kind while concentrating.) During this period, the sorcerer or bard readies her mind to cast her daily allotment of spells. Without such a period to refresh herself, the character does not regain the spell slots she used up the day before.

cleric wrote:

Time of Day

A divine spellcaster chooses and prepares spells ahead of time, but unlike a wizard, does not require a period of rest to prepare spells. Instead, the character chooses a particular time of day to pray and receive spells. The time is usually associated with some daily event. If some event prevents a character from praying at the proper time, she must do so as soon as possible. If the character does not stop to pray for spells at the first opportunity, she must wait until the next day to prepare spells.

Day is literally an undefined term in pathfinder, so it only has its obvious real life meaning as essentially a fluff term in pathfinder. But the thing is that day means so many things depending on where you are, that "daily" abilities is a meaningless term. It's simply per 8 hour rest which lets all of your cast (and uncast apparently, forgot about that swap out rule) spell slots and other "daily" abilities reset, unless you had an interrupted rest and spent them less than 8 hours ago by the time you prepare, in which case you only don't have those specific slots.

The "recovers arcane pool when he prepares his spell" and other similar qualifiers are just there the clarify that you don't get the ability as soon as you wake up (not that you even have to sleep to rest) but you have to spend the preparation time as well.

The problem lies in how you define day on all these different possibilities, especially in a timeless plane of existence. If time is frozen on a plane, can the cleric always instantly refresh his spells, or does it have to be explicitly set when he prays (and can he change when he prays to another time of the day).

Or is "day" simply a shorthand for every 24 hours, regardless of where you are? Honestly, I'd accept that if a gm said that's how they're ruling it, but but by default, there is no definition of day that makes preparation rules make sense with "daily" being anything more than a stand in term.


Has this really come down to arguing about what 'daily' and 'day' means?

They are not defined in pathfinder because they are defined in reality.

Pathfinder doesn't define twenty, so I don't understand which one of these undefined shaped dice to roll for initiative...

If you can't reconcile daily meaning once per day you're being intentionally obtuse.


To avoid having the maguses spell preparation ratchet to later and later times during the day (I was 5 minutes late preparing this morning, so I'll be 5 minutes late forever!) you need to define daily as being once-per-sidereal-day, not a 24 hour timer. Since the 5 minutes late forever thing is silly IMO I go with once per sidereal day - and if you somehow get to a planet with a longer or shorter day leave that sidereal day defined by Earth/Golarion/equivalent.

You are really trying to argue that it is possible to prepare the same slots more than once a day?

Because, if you are trying to say that, you are missing a key part of the table defining all classes abilities:
Spells per Day

BTW, day is defined:

The Inner Sea World Guide wrote:

TIME

Although many calendars exist among the peoples of the Inner Sea, the one in widest use employs Absalom Reckoning (ar) for all of its dates. This reckoning system is based on the foundation of Absalom (which occurred on 1 Abadius, 1 ar), and because of Absalom’s expansive influence, the city’s calendar has achieved great popularity throughout the region. In Absalom Reckoning, the day of the month is always given first, followed by the name or number of the month, with the year coming last. Golarion spins on its axis roughly once every 24 hours. A week consists of 7 days, with 52 weeks per year. A year has 12 months, each of which corresponds to a popular deity and (roughly) to a single cycle of Golarion’s sole moon. In order to most accurately reflect reality, many calendars across Golarion add in leap days. In the Absalom Reckoning, the leap day is tacked on to the end of Calistril and occurs on every year divisible by 8. Thus, the current year (4711) is not
a leap year, but 4704 was and 4712 will be.


it's good to have a hobby, keeps you out of trouble. (ゝ╹ᗜ╹)/✽


Wizard is already the best class in the game and now you want them to be able to prep spells 2x or 3x per day?
