Needs Better Explanation[edit]

The first two times I read through this feat, I didn't understand it at all. This begs for a more clear explanation of how to use it. Surgo 13:02, 5 April 2009 (MDT)


A better Explanation, And Commentary[edit]

As written, this feat is not balanced. I would consider to be "broken", "overpowered", and unacceptable for general use.


In order to be better understood, the feat could be re-written as follows:

Mana-based Casting(clarified) [Arcane][edit]

Character may memorize "Mana" instead of any spell slot. "Mana" can be expended to spontaneously cast a spell.
Prerequisite: Any three metamagic feats.
Benefit: you may cast any spell you know, or that is contained in your spellbook, spontaneously. Whenever you cast a spell, instead of using a spell slot of that spell's normal level, you may pay any number of spell slots whose total level equal the level of the spell you intend to cast.
Normal: Casting a spell expends a spell slot of the same level as the spell cast. Additionally, prepared arcane casters must prepare their spells in advance.


Notice the problem? I would hate to fight against a wizard like that could do that. Psionics lets you do something similar to this, but in return they get fewer "spells" each day, AND their "spells" don't scale with caster-level unless you use a higher level slot.

Moreover, I remember a certain class feature of the Ur-Priest gained at level 6 (character level 11):

Siphon Spell Power: once per day, an ur-priest may sacrifice two or more lower level spell slots to gain a single spell slot of a higher level. Add the spell levels of all sacrificed spell slots and multiply the total by 3/4. The ur-piest gains one spell slot of this spell level. (paraphrased for briefness and clarity)


The feat in question--Mana based spellcasting--would be noticeably more powerful than this class feature. My personal suggestion, if you want this kind of ability is to use psionics. That said, the following re-write should make the feat playable:


Mana-based Casting(new) [Arcane][edit]

You have gained such an understanding of the manipulation of magic that you can now break out of the normal bounds of prepared spellcasting designated spell slots and spell levels. Sadly, your freedom comes at a price, and your methods are slightly less efficient than the regimented norm.
Prerequisite: Any three metamagic feats.
Benefit: When preparing spells, you may choose leave up to one spell slot of each spell level you can cast empty. You lose these spell slots, but instead gain a number of points of mana equal to two times the combine spell level of all spell slots lost this way. This change remains in effect until the next time you choose to prepare spells.

A spontaneous caster (such as a sorcerer) may cast any spell she knows by expending a number of points of mana equal to three times the spell's level.

A prepared caster (such as a wizard) may cast any spell which they have selected with the spell mastery feat, or which they have gained the ability to cast spontaneously (a spell cast from a runestaff, for example) by expending a number of points of mana equal to three times the spell's level.

Cantrips require only 1 point of mana to cast.
Normal: Casting a spell expends a spell slot of the same level as the spell cast. Additionally, prepared arcane casters must prepare their spells in advance.


Notice that this gives a somewhat worse return than either of the previous models, giving you a total number of effective spell slots equal to 2/3 the number you gave up. Such is the price of flexibility.


The following feats are a logical extension to the one I have presented:


Improved Mana-based Casting [Arcane][edit]

You are allowed even more mana with which to cast your spells freely.
Prerequisite: Any three metamagic feats, Mana-based Casting
Benefit: When preparing spells, you may leave up to twice as many spell slots empty, in order to gain up to twice the mana from you Mana-based Casting feat (two spell slots of each spell level you can cast). Additionally, you regenerate 1 mana per hour.
Normal: You regenerate mana only with a full 8 hours of rest.


Improved Mana Regeneration [Arcane][edit]

You have a seemingly endless supply of mana.
Prerequisite: Improved Mana-based Casting
Benefit: You regenerate an additional amount of mana each hour equal to 1/4 your caster level (round down). If you do nothing but rest during this time, add an additional 1 to the total regenerated each hour.
Normal: you regenerate only 1 mana per hour.


One final Note:

There is no reason why this feat should be restricted to only Arcane casters, and according to the prerequisites, it is fully available to Divine casters as well.

one more feat to add:


Greater Mana-based Casting [Arcane][edit]

You have learned to separate your mana into finer segments; this does not so much allow you to wield more magical power as it allows you a more efficient use of the mana you already possessed.
Prerequisite: Any three metamagic feats, Mana-based Casting
Benefit: for each spell slot you sacrifice, when you preparing spells each day, you gain an amount of mana equal to three times the combine spell level of all spell slots sacrificed in this way. You also gain an additional number of points of mana equal to your spellcasting ability modifier. Casting a spell using mana now requires 4 points of mana, per spell level, rather than three. A Prepared caster may also prepare up to 2 spells/day which they may cast using only their mana pool (these spells do nat take up spell slots, and may be of any level the caster could normally cast).
Normal: you gain 2 mana per spell level sacrificed durring preparation, and casting a spell costs 3 mana per spell level.
