Let's do everything in no time in D&D 3.5.
The build: Warforged Eidetic Wizard (Battle Domain (http://www.d20srd.org/srd/variant/classes/variantCharacterClasses.htm#battleDomain)) 5/Incantatrix 10/Wyrm Wizard 1/Loremaster 1/Wyrm Wizard 1(Favor of the Martyr)/Lore Master 2
Feats:
L1: Unarmored body. Feat tax for Warforged Wizards.
L3: Maximize Spell. A critical Metamagic.
Wizard 5: Invisible Spell. For Arcane Thesis, but also handy.
Otyugh Hole: Iron Will. Prerequisite feat tax.
L6: Eschew Materials. Optional. Eliminates "realism" issues related to casting infinitely many spells with a finite spell component pouch.
Incantatrix 1: Cooperative Spell. For Arcane Thesis
L9: Arcane Thesis[Celerity]. Extra actions anyone?
Incantatrix 4: Twin Spell. A critical metamagic.
L12: Arcane Thesis[Shroud of Flame]. Our absorption power source.
Incantatrix 7: Energy Substitution[Cold]
L15: Skill Focus(Knowledge[any]). Prerequisite feat tax.
Incantatrix 10: Repeat Spell. A critical metamagic.
L18: Arcane Thesis[Absorption]. Unlocks infinite spellcasting.
Loremaster 3: Arcane Thesis[Timestop]. Unlocks infinite actions.
Attributes don't matter, except we need Intelligence 20 for the Loremaster bonus feat.
No items needed. We took Eidetic wizard so there isn't even a spellbook.
Using this build we can initiate a Time Stop loop.
A cold start requires 3 rounds.
Round 1: Cast Favor of the Matyr. This is a 4th level spell that eliminates the daze downside of Celerity.
Round 2:
Standard action: Cast Repeat Maximized Cooperative Invisible Absorption (RMCIA), a 9th level spell with metamagic reduction.
Swift action: Cast Twin Cooperative Invisible Celerity to get 2 standard actions this round. This is a 4th level spell.
Standard action: Cast Repeat Twin Esub[cold] Cooperative Invisble Shroud of Flame (RTECISoF) targeting yourself. This is a 5th level spell that charges up Absorption to free cast up to a 10th level spell.
Standard action: Free Cast Shapechange (http://www.d20srd.org/srd/spells/shapechange.htm).
Free action: Shapechange[Chronotyryn].
Round 3:
no action: Maximized Absorption repeated.
no action: RTECISoF repeated charging Maximized Absorption
Standard action: Free cast RMCIA
Chronotyryn Standard action: Cast RTECISoF charging Maximized Absorption
Swift action: Cast Repeat Invisible Celerity (RIC) for one standard actions this round and 1 standard action next round
Standard action: Free Cast Maximized Invisible Time Stop (http://www.d20srd.org/srd/spells/timeStop.htm) (MITS) to get 5 rounds of apparent time. This is a 9th level spell.
At this point, you start acting in apparent time while the world blinks. The first round of apparent time looks like this:
no action: Maximized Absorption repeated.
no action: RTECISoF repeated charging Maximized Absorption
no action: Celerity repeated
Standard action: Free cast RMCIA
Standard action: Cast RTECISoF charging Maximized Absorption
Chronotyryn Standard action: Free cast Repeat Lucubration (http://www.d20srd.org/srd/spells/magesLucubration.htm) (RL) to recover one chosen L5- spell.
And the next like this:
no action: Maximized Absorption repeated.
no action: RTECISoF repeated charging Maximized Absorption.
no action: Lucubration repeated recovering one L5- spell.
Standard action: Free cast RMCIA.
Chronotyryn Standard action: Cast RTECISoF charging Maximized Absorption
Swift action: Cast RIC to get 1 standard actions this round and 1 standard actions next round.
Standard action: Free cast RL to recover one chosen L5- spell.
This repeats indefinitely, occasionally casting MITS or other spells instead of RL.
Using this loop, every round we can cast one spell of any level for free. Every 5th round we must cast Maximized Time Stop. We need to cast one L5 spell to charge absorption every round and one L5 spell every other round to get enough actions. Hence, over 10 rounds we can cast 2x maximized Time Stop and 8x Repeat Lucubration while powering the loop with 15 L5 spells. Since 8x Repeat Lucubration recovers 16 L5- spells and we only use 15 L5- spells, We never run out of spells. We can also:
Recover an extra L5- spell every 10 rounds.
Cast any full-round or less spell for free every 20 rounds of apparent time. That is: 720 free spells / day of apparent time.
Move.
How long can this go on? Forever (and in no time at all)
We can cast Favor the Martyr every 19 minutes (190 rounds) for free to keep it always up.
We can cast Shapechange every 190 minutes (1900 rounds) for free to keep it always up.
As a Warforged, there is no need to sleep, eat, or breath.
As a Warforged, there is no age limit.
What is the cost of doing this? The initial casting of Absorption is not free so we must memorize 2x Repeat Maximized Absorption, Shapechange, and Maximized Time Stop with level 9 slots, Repeat Lucubration with a level 8 slot, 3x Repeat Twin ESubst[cold] Cooperative Invisible Shroud of Flame with level 5 slots, and Twin Cooperative Invisible Celerity, Repeat Invisible Celerity, and Favor of the Martyr with level 4 slots.
Two tricks enhance this further.
The spell Rary's Arcane Conversion allows you to exchange any wizard spell for any other spell of the same level or less. To take full advantage of this, we need a free wizard spell slot at every level. The only difficult level is 9 for which exactly one extra spell slot is available since Time Stop comes from the Battle Domain.
Normally, you cannot effect a creature while in Time Stop. However, by using ready actions at the end of Time Stop we can affect creatures just after Time Stop ends, but before they can act, then resume Time Stop.
This is slightly tricky because ready actions happen before their condition, ready actions alter initiative, and Repeat Spell is initiative dependent. Ready action resets your initiative to when it goes off in the next (real-time) round while Repeat Spell goes off "at the beginning of your turn" (i.e. before you act). Let's also use metamagic spell abbreviations from the Time Stop loop above (RIC, RMCIA, RTECISoF, MITS). Let's assume that in the last round of Time Stop we did not cast RIC since that can always be arranged. The sequence looks like this:
Swift action: Cast Celerity granting a standard action this turn.
Ready Action, Condition: Any action, Action: Free Cast RMCIA.
No action: Time Stop ends.
No action: Maximized Absorption repeated.
No action: RTECISoF repeated charging Maximized Absorption.
No action: Lucubration repeated, recovering an L5- spell.
Triggered Action: Free Cast RMCIA (This reset your initiative. All repeat spells must go off before it.)
Immediate Action: cast TCIC granting two standard actions this turn. (This triggers the ready action and is cast before anyone else acts.)
Standard action: <any standard>
Standard action: Cast RTECISoF charging Maximized Absorption
Chronotyryn Immediate action: cast Celerity granting a standard action.
Standard action: cast MITS.
At this point Time Stop resumes.
We have infinite actions and infinite spells but Timestop still imposes limitations.
Normal and magical fire, cold, gas, and the like can still harm you.
Planar Bubble (3 hour duration), Energy Immunity (24 hour duration), and various other spells resist essentially all environmental effects and are easily recast as needed.
...other creatures are invulnerable to your attacks and spells; you cannot target such creatures with any attack or spell.
Using the Killer Time Stop loop above, we can cast (and later recover) any L5- spell. Pretty much every creature is vulnerable to some L5- spell.
You cannot move or harm items held, carried, or worn by a creature stuck in normal time...
This can be avoided by converting a creature into a corpse with a sufficient number of L5- spells.
You cannot enter an area protected by an antimagic field...
You can however cast Disjunction (http://www.d20srd.org/srd/spells/magesDisjunction.htm) as often as desired, eventually eliminating any AMF.
The surviving limitation are:
We cannot effect creatures with L6+ spells or in ways requiring more than a standard action.
We cannot take or harm a creature's items unless we kill it first. Not even Disjunction works.
We cannot cast spells with expensive material components, XP costs, or other expenditure requirements.
We cannot cast spells with more than a full-round casting time.
While these are significant, they still leave many possibilities. Interesting options include:
Disintegrate a planet.
End a wight apocalypse.
Dispel every spell.
There are a few other proposed approaches for infinite spells which require either breaking the rules or a permissive interpretation depending on your point of view.
Use Arcane Fusion to cast Sanctum Arcane Fusion and a level 1- spell. Since the effect of Sanctum spell (away from your sanctuary) is to lower the level of a spell by one, Sanctum Arcane Fusion qualifies as a 4thlevel spell which you can cast inside (Greater) Arcane Fusion.
This approach is counter to RAW because Arcane Fusion was errataed to allow casting of metamagic so long as the metamagic-adjusted spell level is level 4-. However, the metamagic adjusted spell level of Sanctum (Greater) Arcane Fusion is 5th (or 8th). See here (http://www.giantitp.com/forums/showsinglepost.php?p=21029504&postcount=18) for a more detailed discussion.
Here. (http://www.giantitp.com/forums/showthread.php?280365-Priya-the-Prismatic-Priestess-Buffs-Across-the-Spectrum)
Use Spelldancing with Maximized Repeat Twin Timestop and Repeat Maximized Absorption to cast all spells desired inside of timestop.
If 'apparent rounds' is an effect of Time Stop, then the effect of Maximized Repeat Twin Time Stop is 5 rounds of apparent time, not 20 due to stacking effects (http://www.d20srd.org/srd/magicOverview/castingSpells.htm#stackingEffects) rules. Maximize (which only works on effects!) turns 1d4+1 rounds into 5 rounds. Twin Spell does nothing. If Repeat spell goes off at the beginning of your next apparent turn (i.e. the first turn in the first Time Stop) then the two overlapping Time Stops provide the same effect twice implying no change to the number of rounds of apparent time. If the Repeat Time Stop goes off at the beginnning of the caster's turn in the next real-time round there is an opportunity for the world to act for one round between Time Stops.
A similar issue exists with Absorption. If Absorption capacity is an effect, then Maximized Absorption provides capacity for 10 spell levels while Twin does nothing. Repeat only works if the absorption capacity is used before the repeated spell is cast.
Altogether, it's clearly impossible to use Priya since Repeat Maximized Absorption requires 6 rounds of Spelldancing while Maximized Time Stop requires 5.
The Absorption charging mechanism is also problematic. Priya lists (persisted) Glorious Master of the Elements, Stormrage, and Celestial Aspect. Absorption says:
Absorption absorbs only ranged spells that have you as a target. while all of these spells allow launching multiple ranged attacks, only GMotE is actually a ranged spell according to it's stat block. GMotE has a text clashing with the description so what it does precisely is unclear. The effects of Absorption are also somewhat murky. Does it capture all of the spell energy, hence blocking effects on other targets? Or does it just block the spell from effecting you? The rod of absorption (http://www.d20srd.org/srd/magicItems/rods.htm#absorption) is more narrowly targeting (only applying to single-target spells) and has a clearer effect (nullifying the spell).
Below Cruiser1 suggests a modified version of Priya could work. Overall, this seems to still require a permissive interpretation of the rules, but the approach can address some of the issues.
The modification is to use Repeat Empower Absorption with Shapechange[Chronotyryn] (for dual actions) and persistent Arcane Surge. Repeat Empower only requires 5 rounds to Spelldance. If we neglect issues of Absorption charging, this approach allows creating a Time Stop loop since a Chronotyryn can simultaneously Spelldance a Maximized Time Stop to go off at the end of round 5 just after Repeat Empower Absorption is cast (and charged). However, this clearly does not allow for casting multiple Repeat Empowered Absorptions per Time Stop, a prerequisite for the ability to cast any spell for free. Instead, the best case is being able to cast level 6- spells for free (Maximum Absorption capacity = 15 - 9 for Time Stop or Absorption = 6). This can be fixed by reducing metamagic costs via Incantatrix 10 (for example). A Spelldancer 1/Incantatrix 10 could cast Repeat Empowered Absorption in 3 rounds and Maximized Empowered Time Stop in 3 rounds granting at least 6 rounds of apparent time, implying any spell level 9 or less can be cast for free in a Time Stop.
To address Absorption charging issues you could try to use Repeat Maximized Empowered Absorption which has a minimum of 10+3-9 = 4 levels of unused absorption capacity. This would require something like a Spelldancer 1/Incantatrix 10/Halruuan Elder 4 to reduce the rounds of spelldance to 3 with Adroit Casting for Maximize Spell and Repeat Spell. A Twin Sanctum Heightened spell cast in your sanctum with Earth Spell by an Illumian with Improved Sigil(Krau) could turn this into 14 levels to power Absorption with 3 rounds of Spelldancing by an Incantatrix 10. Unfortunately, there seems to be no way to make this work w.r.t. action economy since you need to cast Absorption, an Absorption charging spell, and Time Stop all in the same round and all of these would require Spell Dancing in advance. You can't spelldance for 3 spells simultaneously with Dual Actions: 2 is the maximum.
I don't see any way to execute Killer Time Stop effects. In essence, you fundamentally cannot wait until Time Stop ends to cast Time Stop because initiative is reset to the point where a readied or delayed action executes. This implies Absorption is repeated before you can cast Time Stop which implies you don't have a charged Absorption to cast the next Absorption. The clockworks wizard gets around this by casting a Repeat Maximized Absorption, charging the Absorption, and then casting Time Stop between when the Time Stop ends and anyone else acts.

This was my previous attempt. It still relies on nested Time Stop for accumulation of apparent rounds. If nested Time Stop does not accumulate apparent rounds due to the "Same Effect More than Once in Different Strengths" rule then this does not work.
It also relies on Lucubration to allow a familiar to recover a cast spell that was granted via Imbue Familiar with Spell. This application might work, but it is a nonstandard use of the spell and hence might not. The conservative ruling is that it does not.
