Calculate DC

[prospero977]

Hello All,
I'm trying to figure out how to calculate DC, as from what I've read this particular roll becomes super important later on in the game.

Here is what I assume:

Spell DC = 10 + relevant ability mod [here CHA]+ spell level [here influenced by heighten]+ Spell Focus feats [both stack] + item [only highest bonus counts, different items stack in no way].

So, I'm not sure how to figure the ability mod part.

I'm a level 7 with 22 CHA (+6 Mod). Does that mean:

10 + 22 + spell level + focus + item

Or:
10 + 6 + spell level + focus + item


Finally, then, are the enhancements that directly increase charisma the only ones that will have an impact on DC?

Thanks,
Pros

The second one. with 22 charisma your ability modifier is 6. As with all stat-dependent characteristics (except carrying weight) your ability scores only affect your class features/etc. when on even numbers, they utilize your modifier not the score itself.

10 + spell level + 6 + x focus + x item

and yes, only cha enhancements will impact directly


for perspective, a very high endgame dc looks like

10 + 15 cha (40 cha) + 9 level + 1 item + 1 focus = 36

Very Helpful:

So, the spell focus feats are helpful, especially if you stack two, but charisma based enhancement is the way
to really amp it up.

SF feats are great but limited becuase they are limited by school .. spending 2 feats to be good with just a few of your spells isn't always a good idea, it tends to work beter with wizards since they get their metamagics for free so have more feats to burn

DC are pretty important end game.

36 is decent, I would shoot for at least that.
39 is pretty easily achievable for an end game sorc as a practical running DC.
40 is uber with every practical thing out there (41 for wiz if you dont mind dying occasionally).

You can bump these numbers by one if you buy a store pot. However, the 10 minute duration and cost really make this only good for special occasions.

Assuming spell focus for 2 and an item for +1, tiny, you're assuming a 44 charisma as 'pretty achievable', when, in fact, that is the maximum available with all enhancements.. 40 is only available through the use of a greater spell focus item, which is only available on 2 handed weapons, and would require you to both use a +2 cha tod ring and a +1 exceptional cha dragontouched. There is no one who's running with a 39 on a regular basis, or with more htan a few spells (since 2 spell focus feats are required to achieve it).

44 charisma is only available to a +4 tome/litany having drow, which to my knowledge there aren't any yet, since I imagine someone would have posted it.


Also, all your numbers are only achievable with yugoloth pot usage, and they last 15 minutes, carry through instances and are prohibitive for wizards (-50% fortication on the int potion) and not at all for sorcerors (1k plat each, 15 minutes for -4 fort save), wiz and sorc endgame normal dcs are identical, the capstone has no bearing unless you're willing to suffer with sub-100% fort.
suggesting that use of 2 spell focus feats and a +4 tome is a normal, achievable goal is patently misleading.


edit: or you're suggesting the constant presence of a spellsinger, which is equally unrealistic.
