[d20 Feat] Probablility Spell

What do you think the level adjustment for this one should be?

QuoteProbability Spell (Metamagic)

Your knowledge of probability infuses your spells with energies which make them at times harder to resist and other times easier.

Prerequisite: spellcraft 5 ranks

Benefit: Your spells which involve a save adjust the DC of that save by d6-3.

I'd think it would be fine as is and no adjustment but I might not be seeing the whole picture.

I'm thinking of taking care of Wild magic through a feat tree in case anyone is wondering why I'm doing this at all.

It's nice as written. Simple and easy to use.

I'd kind of like a mechanic where you could choose how much you wanted to adjust the spell, like somehow, at higher levels, you could use a d8, d10, or d12 instead of the d6. It's not powerful enough to make it a feat tree, so it would all have to be rolled into this one feat somehow.
Next phase, new wave, dance craze, anyways, it's still rock and roll to me.

You can talk all you want about theory, craft, or whatever. But in the end, it's still just new ways of looking at people playing make-believe and having a good time with their friends. Intellectualize or analyze all you want, but we've been playing the same game since we were 2 years old. We just have shinier books, spend more money, and use bigger words now.

That would be an easy metmagic feat to write up.

QuotePotent Spell (Metamagic)

You have mastered the ability of increasing the numeric variables of magic

Prerequisite: spellcraft 9 ranks

Benefit: For each +1 spell level you are willing to add to your spell you may increase the damage dice by one category. d6 to d8, d8 to d10, d10 to d12. Example your fireball does 10d12 if your add +3 spell levels and use a 6th level slot to cast or memorize it.


This puts it on par with Maximize spell, it could do more but likely won't.

I think Merak meant that the save DC could adjusted by d6-3, d8-3, d10-3 or something similar.

Imo the feat's fine without level adjustment.
Any dream will do

I was thinking d6-3, d8-4, d10-5, and d12-6, to maintain the "equal probability of good or bad consequences" feel.

Ah.

Then it would require a scaling clause to the feat which should be voluntary.

QuoteSpecial: The caster may at their discretion coose to add the results of d8-4, d10-5, or d12-6 to the DC of their spell.

As a DM I'd be fine with adding that cause it will screw as often as it boons ya.
 

Thjalfi

hmm. actually, I think that on average you're looking at higher save DCs.

a d8 has an average roll of 4.5, right? so if it's only -4, you're looking at, over time, spell DCs on average of .5 higher than average. I do rather like the mechanic so far, though.

howbout making it just a little more complicated, and say that the spell dc is increased by 1d8 minus 1d8? that way you maintain the perfect average and work within the same realm of variability.

I don't really have a problem with that. After all, you are spending a feat on it.

I like it, but to me Wild Magic should have more of an oops, that Fireball came out as a cloud of butterflies feel, than an oops- he saved against my Fireball because I rolled poorly to adjust the Save DC feel.

For Full-on wild magic, arrange all the spells into domain lists.  When you cast a spell, make a spellcraft check.  The DC of this check is 10 + (double the level of the spell)

If you fail, rols 1d6:

1. You cast the next spell up the list - if you were casting the 3rd-level fire spell, you cast the second-level fire spell instead.

2. You cast the next spell down the list - if you were casting the 3rd-level fire spell, you cast the fourth-level fire spell instead.

3. You cast a spell of the correct level, but from the wrong domain (roll randomly).

4. You cast the spell correctly, but it costs you a spell slot one level higher than it should (if you have no such slots, cost is normal).

5. You cast the spell correctly, but it costs you a spell slot one level lower than it should (if you have no such slots, cost is normal).

6. Roll 2d12, one after another.  Add the first roll to the save DC of the spell; subtract the second.

...........

The side effect of #4 and #5 is that it's now very slightly in the interest of the mage to start off the day by blowing through their biggest spells and working down the list, so they never have to "pay extra" and sometimes "get a bargain".

Okay.  I like that.  It would take some bookwork to draw up domains so that a Wizard/Sorcerer Wild Magic-user has his spell list spread across some interesting domains.

I'd also recommend that a random table be drawn up for conjuration spell results, so that my afore-mentioned cloud of butterflies is possible as well as fun stuff like raining cats and dogs and hailing taxis.

Just use the list from the Wand of Wonder.
