Under the new spell point system, metamagics are very much out of line with where they should be (from a balance perspective), as in the example of a 4 point empowered and maximized level one spell costing stupid amounts of spell points to maximize for almost no returns when compared with a level nine spell.
I'm using the feats [Empower and Maximize for this example, but a similar concept applies equally to other metamagic feats. I realize there have been several other threads on the subject, but I did not want this to be buried.
To balance this, I would like to suggest that the feats should have a flat cost associated with the spell level, such as:
Suggestion One (by spell level):
Empower
- Your spells do 50% more damage, at the cost of 2 additional mana per spell level (maximum cost to empower a level 9 spell would be 18 mana, less enhancement reductions - this is only three points higher than the current base of fifteen points to empower).
- Regardless of metamagic enhancements, spell cost for empower must always be at least 6 mana.
Maximize
- Your spells do 100% more damage, at the cost of 3 additional mana per spell level (maximum cost to maximize a level 9 spell would be 27 mana, less enhancement reductions - this is only two points higher than the current base of fifteen points to maximize).
- Regardless of metamagic enhancements, spell cost for empower must always be at least 7 mana.
Suggestion Two (by caster level):
Empower
- Your spells do 50% more damage, at the cost of 2 additional mana per caster level, up to a maximum of 18 at caster level 9 (maximum cost to empower a spell at caster level 9 would be 18 mana, less enhancement reductions - this is only three points higher than the current base of fifteen points to empower).
- Regardless of metamagic enhancements, spell cost for empower must always be at least 6 mana.
Maximize
- Your spells do 100% more damage, at the cost of 3 additional mana per caster level (maximum cost to maximize a spell at caster level 9 would be 27 mana, less enhancement reductions - this is only two points higher than the current base of fifteen points to maximize).
- Regardless of metamagic enhancements, spell cost for empower must always be at least 7 mana.
With the new reductions in spell point costs, this is almost exactly the system in place now, and would only require adjusting the existing feats to benefit lower level casters. It would balance out the lower level use of these feats, and only slightly increase the higher level use of these feats. With the current (huge) reduction in spell costs, the extra few points to maximize or empower would balance itself out - improving the feats at lower levels, and keeping them as they are at higher levels.
Enhancements and items would then further reduce that cost in the same manner they currently do, requiring no additional balancing, change, or extra code work on part of the development team (or server hamsters).
*** Good point raised by Xenostrata ***
We would not want low level spells costing nothing to maximize.
Check out Suggestion Two In this way it becomes impossible for a caster to get 'free' spells, as total caster level is examined when looking at metamagics and their application - so you would have to pay the fee for spell points irrespective of any splash or other levels. One could tie a minimum cost to activate metamagics (much like necro abilities, etc).
Godzilla would love it.
