--------Fundamental Idea--------
- If you spam enough metamagic with arcane thesis/improved metamagic, etc. some spells are very good
- evocation spells become useful
- healing spells become useful
- debuffs become incredibly dangerous
- action multipliers (celerity, arcane fusion, etc.) are insane
- Spells that grant spells! (I'm focusing on this one)
- You have to be a little careful with the wording (spells slots, Spell Level, prepared spells, you can cast, etc.)
I've seen a lot of threads on this topic, but never one that looked at it holistically. (Arcane Thesis Abuse, Celerity Abuse, Arcane Fusion Abuse, etc.).
--------Metamagic Altering--------
Adroit Casting (Repeat, Twin, or Echoing)
Improved Metamagic
Practiced Spellcaster (Repeat, Twin, or Echoing)
Arcane Thesis (Spell in Question)
Metamagic School Focus
--------Meta Effects----------------Feats / select abilities--------
- Repeat Spell
- Twin Spell
- Share Spells ability of a familiar
- Echoing Spell - "cast as normal, returns *as if it had been prepared again* [aka, into a spell slot] at -4 CL in 1 hour"
- Residual Metamagic
- Sanctum Spell - a sanctum spell has an *effective spell level* 1 higher than its normal level if cast in your sanctum, but if not cast in the sanctum, the spell has an *effective spell level* 1 lower than normal. It uses a spell slot of the spells normal level.
- Circle Magic (from Ghostwalk or Prestige Class - for use with Echoing Spell)
- Heighten
- Versatile Caster - you can use two *spell slots* of the same level to cast a spell you know that is one level higher)
- Arcane Preparation for a Sorcerer (to qualify as a prepared caster)
- Spontaneous Divination for a Wizard (to qualify as a spontaneous caster)
--------Some Key Thoughts--------
--------Generic Build repeat/echoing specialist--------
Human
Wizard (Spontaneous Divination) 5/Incantatrix 10/Halruaan Elder 5

12 Practiced Spellcaster (Repeat)
12 Repeat Spell (Bonus Incantatrix)

15 Versatile Caster
18 Sanctum Spell
Abilities of Note:
Adroit Casting (Echoing, Repeat)
Practiced Spellcaster (Echoing, Repeat)
Improved Metamagic

Circle Magic
So, you can have as many spells as you want (depending on your level of cheese).
An Echoed, Repeated, Extended buff that is 1 min/level will have an effective duration of 14 hours!
EDIT: You can also cast _every_ spell as a Repeat, Echo spell. Meaning every spell prepared becomes prepared twice, and each of these 2 preparations recovers 1 hour after cast => ~ each slot is like have a spell prepared ~14 times.
Best,
