You're banning Automatic Metamagic Capacity but not Improved Metamagic? Shouldn't it be the other way around? Splitting AMC and ISC back into two different feats and banning Improved Metamagic leaves casters in a strong but not incredibly unbalanced position, assuming you do the smart thing and cap the damage of certain uncapped spells (Force Missiles, Avasculate, Maw of Chaos) and restrict Twin Spell and Repeat Spell in the same way that you restrict Quicken Spell (This change makes the ISC AMC combination scale linearly rather than quadratically with level). Perhaps a general proclamation that all spells that deal damage that scales with caster level cap at 25th level unless they explicitly have a cap at a higher level, and benefitting from more caster levels requires the application of metamagic. I usually make Enhance Spell just say "you can benefit from 8 additional caster levels in the case of capped spell effects".
I'm already decided upon what I'm gonna do with Improved Meta-Magic. It will only affect certain meta-magic abilities excluding Quicken, Twin, Repeat and a few others. All of the abilities it actually effects will be included in the actual ability description once it's finished. As far as AMMC goes I like the fact that you have a separate feat for being able to apply MM feats to spell like abilities. It seems like a good idea to me. For epic spellcasting from Feanmerc I'm considering bringing back Both the "Epic Spellcasting" epic feat and "Improved Spell capacity" epic feats, using FeanMerc rules of course, But limiting Improved Spell capacity in some way, or perhaps even empowering it depending on what the numbers say.
[MENTION=80514]Bel[/MENTION]z & Buugi - Either of you two have data crunched on ISC and how well the damage scales?
Of course, to really fix the spell system you'll need to fix save-or-lose spells, but that's a much bigger problem with the game than just spells.
Get rid of them? Maybe. I think limiting how much actual damage they can do in some way might suffice.
Since spellcasters basically stop advancing once they hit 20th level without feats, stacking feats are pretty much required. Things like school specialisation, portfolios and prestige classes will mean casters aren't short on options to make them unique. Maybe there could be a DvA that did the job of either AMC or ISC and scaled with caster level, but there's no way that's going to be balanced.
Well, to be honest there is no point in taking levels in any spellcasting class beyond level 20 aside from bonus epic feats which can be stacked into infinity. However stacking extra Improved Spell Capacity feats does nothing if you don't have enough meta-magic or a high enough spellcraft check to take full advantage of it. Fine, stackable feats are acceptable, but stacking them beyond a certain point NEEDS to become redundant, or else the divine ability multifaceted will become INSANELY overpowered and overused.
I made a separate feat (Innate Metamagic Freedom) to do that. It lacked the prerequisites of Metamagic Freedom because none of them made sense with SLAs. Requiring ranks in Spellcraft and four metamagic feats means that SLA-users who want to take it have to take four useless feats and put ranks in a useless (possibly cross-flavour) skill to get it. And many of the 9th level portfolio spells are really good, so giving spellcasters the ability to metamagic them up for free hardly helps balance.
I may well adopt this rule, at least for purposes of this tournament. Any objections friend?
I'm of the opinion that Cosmics should apply to specific class-features only sparingly, and Transcendental abilities and above should never be class-specific, so metamagic at that level isn't a great idea. Divine Metamagic abilities were something I had considered, but there aren't many that aren't just epic metamagic feats, but better. The ideas I had were: Hyperdimensional Spell (has Transdimensional Spell as a prerequisite, +12 slot adjustment), which affects all coexistent planes simultaneously, like Transdimensional Spell, but also ignores almost everything when calculating line of effect (3D objects don't block LoS for 4D effects), bypasses the miss chance from Interdimensional, and ignores anything an incorporeal touch attack would ignore. Some metamagic effect that gave infinite range (needs Enlarge, +12 slot adjustment) (and another for AoE needing Widen, at +18 slot adjustment). Permanent Spell (needs Extend and Persistent, changes spell duration to Permanent, probably +36 slot adjustment). Interdimensional Spell (prerequisites were Hyperdimensional, Transdimensional, Enlarge and whatever the Divine version of Enlarge is called, +42 slot adjustment), lets you target other planes, although it doesn't let you view other planes inherently, so you're firing blind without some method of remote viewing. Omnidimensional Spell (needing Interdimensional, the Divine version of Widen and all their prerequisites, +64 slot adjustment), lets a spell affect every plane simultaneously. Perceptual Spell (+6 slot adjustment, probably an epic feat) Allows mind-affecting abilities to ignore any immunity to mind-affecting effects other than having an Int of -. Most of those are just beefed-up versions of sub-epic metamagic though. Making Contingency into a metamagic feat might also be a thing.
You have some great ideas man. I love your ideas. You're very intelligent. Thank you so much for being a part of this tournament. -Hugs.-
