Fastest way to level 9 spells?

[Antoine]

A 12th level rogue with 20 CHA, 13 ranks of use magic device, the magical aptitude feat, skill focus(UMD), 5 ranks of spellcraft, and the special ability that lets him take 10 even under stress (5+15+2+3+2) will let the rogue use 9th level spells from a scroll with NO chance of mishap. (DC 37). VOILA!

I sort of remember you can never take 10 on Use Magic Device.
Then the skill mastery won't work since it says you can take ten under stressful conditions, and not that you can take ten with a skill that doesn't allow it.

On the other hand, 5 ranks in Decipher Script will give you another +2 synergy bonus on UMD.

So you'll need :
14th level star elf bard (or any race with +2 Cha/+0 ECL) with 22 Cha
Feats : Craft Wondrous Item (for +6 cloak and total 28 Cha), Magical Aptitude, Skill Focus [Use Magic Device],
Skills : 17 ranks in Use Magic Device, 5 ranks in Spellcraft and Decipher Script
Total +35 Use Magic Device. Completes CL 17/SL 9 sorcerer scrolls 95 % (90,25 % for wizard, druid or cleric scrolls unless 19 Int/Wis as appropriate).

Actually, that's an 80% chance of failure; the 1st level wizard has to make a roll of 17 to successfully cast the thing. (Caster level check with a DC of caster level of scroll +1 = DC 18.)

And must be an Int 19 1st-level Wizard too.

...unless he emulates the high ability score with Use Magic Device. That's probably unlikely to succeed, but it's an option.

A rather difficult option for a 1st level character to strike a DC 34 check in a cross-class skill !
But still an option

Oops! Forgot about that one. On the other hand, with an 8 or better to succeed (thanks to decipher script), he's still a darned good bet, and he could be getting a 50/50 chance at 10th level! (And not worrying about the 19 INT, since he has a +27 in UMD to begin with.)

14th level star elf bard (or any race with +2 Cha/+0 ECL) with 22 Cha
Feats : Craft Wondrous Item (for +6 cloak and total 28 Cha), Magical Aptitude, Skill Focus [Use Magic Device],
Skills : 17 ranks in Use Magic Device, 5 ranks in Spellcraft and Decipher Script
Total +35 Use Magic Device. Completes CL 17/SL 9 sorcerer scrolls 95 % (90,25 % for wizard, druid or cleric scrolls unless 19 Int/Wis as appropriate).

Yeah, but we already have a guy who can do it reliably at 14th level (the Ur-Priest), so if we can somehow get him back below 14th we've got it!

Total +35 Use Magic Device. Completes CL 17/SL 9 sorcerer scrolls 95 % (90,25 % for wizard, druid or cleric scrolls unless 19 Int/Wis as appropriate).

Items: Stone of Good Luck, Scroll of Guidance
These two give another +2 on the check, so you could be an 13th level star elf bard and have +36 on UMD.

Oh. Um... he has 17 friends using Aid Another! Yeah, that's it!
Or he just has a magic item that gives a big skill bonus. He got it in the same treasure hoard where he picked up that 9th-level scroll.

Don't forget the Bard assist with an Inspire Competence.

OK, then : revised star elf bard
Feats : (1) Skill Focus [UMD] (3) Craft Wondrous Items (6) Magical Aptitude (9) Nymph's Kiss
Skills : Use Magic Device 15 ranks, Decipher Script 5 ranks, Spellcraft 5 ranks
Homemade +6 cloak of charisma for a total Cha 28/+9

Total Use Magic Device (scrolls) : +35. (Still misses on a one, so doesn't need more for DC 37).

AT 12TH LEVEL !! We've got it

Can't inspire competence in himself IIRC.

For the same reason of self-reliability, I didn't throw in the stone of good luck. You need a priest to craft one of these.
