Is there a caster that can cast/know any spell?

[thefear436]

As the title suggests is there a caster that can cast/know ANY spell, or is artificer the only one and even that is only for divine spells

[TaintedLight]

There's the Extra Spell feat. It doesn't require the chosen spell to be on your class list.

[Balain]

Mystic Theurge or what ever it is called. Gets both divine and arcane spells. Can't get 9th level spells till epic levels though

[Tael]

Spell to Power Erudites, Artificers*, Warlocks* and potentially Archivists using some cheese can cast any spell in the game.

*: These classes must craft wands/scrolls and then UMD them, but they can craft anything and UMD well.

Mystic Theurge or what ever it is called. Gets both divine and arcane spells. Can't get 9th level spells till epic levels though

Use Ur Priest to get that. Wizard 6/Mindbender 1/Ur Priest 2/Mystic Theurge 10/Arcane Advancement 1.

Depending how you got in you would end up missing spells, there are druid only and bard only spells and I love the heck outta glibness

The recaster PrC can learn spells from any list for your base class, as can Extra Spell (though the latter is arguably not intended). Archivist (not artificer) can learn every divine spell and most arcane ones (thanks to domain lists, divine bard, and similar), as well as cast even more of them (via Anyspell and Miracle). A wizard/rainbow servant can learn/cast every sor/wiz and cleric spell in the game, which is a pretty substantive portion. Domain dipping (via Contemplative, Sovereign Speaker, etc) can get even more.

Finally, UMD users can cast every spell as scrolls, while warlock and artificer can even craft those scrolls for you.

I'd actually argue that that's exactly what the Extra Spell feat is for:

For classes such as wizard that have more options for learning spells, Extra Spell is generally used to learn a specific spell that the character lacks access to and would be unable to research.

[EvilJames]

No there is no class that can cast every single spell in the game. The closest is the Archivist which has been mentioned which can learn any divine spell in the game be they cleric, druid paladin, ranger, blackguard, domain or anything else that says divine spell. And a few prestige classes grant you interesting mixes of spells (usually clerical and sorc/wiz) but no single class allows access to every single spell. Unique spell lists are part of what differentiates many of the classes. If you want bard spells you have to be a bard, if you want wujen spells you have to be a wujen and so on.

It's disallowed via FAQ. FAQ isn't RAW though, so take it as you will.

I didn't know that there was an FAQ on it. I suppose it makes sense to restrict it that way, but that just makes it another poorly written feat.

[Wings of Peace]

Really? No mention of Rainbow Warmages/Rainbow Beguilers at all? Shame on you people!

They don't really come close to the "every spell known ever" limit much more than, say, a cleric with a few extra domain dips. I did mention Rainbow Wizard though, which can learn the entirety of the sor/wiz and cleric lists. It's not nearly as good since it's not spontaneous, but it does serve the OP's purpose better.

[TaintedLight]

Limited Wish gets you any bard spell I think, but you're still short some druid and Dread Necromancer spells with Wizard/Archivist gestalt. Also Wujen.

[Wings of Peace]

Untrue. The original Rainbow Warmage also mixed in Prestige Paladin 4 for Sword of the Arcane Order which granted it Wizard casting.

[JeminiZero]

The straightforward without too much cheese is: Anything with Level 9 Spells + Method of artificially casting level 10 spells + 2 level dip in Chameleon.

Chameleon 2 comes with a feat that can be swapped each day, letting you take Extra Spell Known for 1 particular spell. However, Extra Spell Known is limited to 1 level below the highest you can cast, so you need Versatile/Heighten or Heighten/Earth Spell or Sanctum to fake level 10 spells to qualify Extra Spell Known for level 9 spell.

Now to make it really cheesy, use 18 Archivist/2 Chameleon. As an Archivist, you can write divine scrolls of your extra known spell. The next day you swap out extra known spell for something else. Since you can learn ANY divine spell, you can then copy the divine scroll you scribed previously into your prayer book, permanently adding it to your reportaire.

Ooooo. You just reminded me of the old Ultimate Multi-Threat build. Anyone remember that guy? The idea behind him was that by the rules we can't use Chameleon to qualify for anything but that doesn't stop us from applying lots of things to the Chameleon.

The old Ultimate Multi-Threat used an Illumian with the pseudo DMM Heighten Spell word and another feat (see Earth Spell and it's kin) to qualify as being able to cast level 10 spells. From there we work backwards and take Extra slot 9,8, and 7. This literally gives us access to every spell in existence.

With Magical Training we could theoretically qualify for Tainted Scholar and apply that to Chameleon as well which would blast our spells per day through the roof. Especially if we buy the [Evil] subtype.

[Robert Blackletter]

The Sorcerer possibly can due to this line in the phb

These new spells can be common spells chosen from the sorcerer/wizard spell list, or they can be unusual spells that the sorcerer has gained some understanding of by study.

Though I doubt many DM's would let it fly

[Bayar]

The warlock and artificier would like a word with you...

[Thurbane]

Chameleon casting (arcane focus, divine focus) can be from any arcane casting class and any divine casting class respectively, but only up to level 6.

The Generic Spellcaster class in UA can take any spell from the Cleric, Druid or Sorc/Wizard list (but not from Bard, Paladin, Ranger etc.).

...other than that, theurge or gestalt Spell to Power Erudite/Archivist.

[urbanpirate]

if gestalt is allowed stp erudite//archivist should take care of al spells for ya. also SAD if i remember correctly

[Noneoyabizzness]

spellcaster generic class in unearthed arcana it just chooses spells.

gestalting wiz arch might be the msot efficient way to get EVERY spell (mystic theurge/ bard or hexblade at some point to get some missing spells)

[shadow_archmagi]

artificer is only for divine spells

Uh, NO.

Artificer is for all spells. Quoth the eberron campaign setting

An artificer's magic is neither arcane nor divine. Artificers do whatever they want with any spell they want no matter whose class list it is on.

"I get a better hat than you"

Artificer Tzu said that and I'd say he knows a LITTLE more about crafting than YOU DO pal, because HE INVENTED IT! And then he perfected it so that no man could best him in the test of spite!

Basically, all an artificer has to do to cast a spell of 4th level or lower is burn a 1st level infusion, because one of his powers is "Turn anything into a scroll in 60 seconds or less"

For any spell HIGHER than that, he can make a scroll or a wand or something. Thus, there is no reason (Besides finite supply of Gold and XP) that an artificer couldn't make a scroll of every single spell ever and be COMPLETELY PREPARED.

[fryplink]

with enough cheese you could probably get 9th's on a Archivist/Wizard theurge build. It's also nicely Int friendly. He could theoretically know every spell, but his ability to learn them all *might* be limited by WBL.

[Thurbane]

There's still some spells (Wu Jen uniques, for example) that a Wizard/Archivist couldn't learn...

[Jack_Simth]

Archivist (not artificer) can learn every divine spell and most arcane ones (thanks to domain lists, divine bard, and similar), as well as cast even more of them (via Anyspell and Miracle).

Ah, there's a quirk in the magic item rules that lets the Archivist learn any spell:

It is possible for more than one character to cooperate in the creation of an item, with each participant providing one or more of the prerequisites. In some cases, cooperation may even be necessary.

If two or more characters cooperate to create an item, they must agree among themselves who will be considered the creator for the purpose of determinations where the creator’s level must be known. The character designated as the creator pays the XP required to make the item.

Tack on to that a bit from the Scroll Activation rules

(The type of scroll a character creates is also determined by his or her class.)

, and you have something interesting:

If an Archivist provides the Scribe Scroll feat (a prerequisite for making a scroll), and a member of another class (even an arcane one) provides the actual spell, and the Archivist pays the XP cost, the resulting scroll is Divine (based on the class of the 'creator'). Which the Archivist can learn, what with it being a Divine scroll.

So with enough work, an Archivist can learn any spell in the game (but not Psionic Powers). The Spell to Power Erudite (variation on a variation of the Psion - check Complete Psionic) can also learn any spell in the game.

[JBento]

The pure wizard can do the exact same thing, since he can scribe any spell from a magical scroll into his spellbook. EVEN if your DM restricts this to arcane spells, there's no shortage of critters (dragons, nagas, etc.) that cast Cleric and + spells as arcane spells.

Quote, from the srd:

Spells Copied from Another’s Spellbook or a Scroll

A wizard can also add a spell to her book whenever she encounters one on a magic scroll or in another wizard’s spellbook

EDIT: There's an optimization challenge somewhere on the boards where Kurald Galain made a gestalt character that could do every frikkin' magic trick - spells, powers, invocation, soulmelds, vestige binding, the works

[Greenish]

The Omnicaster? I seem to recall that it was a gestalt that used double progression PrCs on both sides, but yeah, it was cool. It even had Utterances (truenamer magic).

2 Wizard/8 Beholder Mage/10 Rainbow Servant

Requires incredible cheese. Can learn every arcane spell, knows every divine spell ever published, and can cast all of them spontaneously.

I don't recommend ever trying to pull this off.

You won't get bard spells, but I don't think you'd really care anyway.

EDIT: Oh, I forgot to mention, at level 20 you can also cast 10 spells in 1 round, if you wanted to.

[fryplink]

You won't get bard spells, but I don't think you'd really care anyway.

I think the only bard spell not to appear on another list somewhere is sympathetic vibration

Edit: in core that is, a lot of the other bard-exclusive spells involve bardic music, making it a bit silly to have.
