Bonus to untyped rolls? [3.5]

[TroubleBrewing]

Is there a feat, spell, class feature, ANYTHING at all that gives a bonus to any roll at all? For example, True Strike gives a +20 insight bonus on your next attack roll. Is there anything that gives a +[any] [insight, competence, luck, exalted, vile, feat, equipment, etc] to any roll?

[TroubleBrewing]

Also, is there any kind of guide online for optimizing ability scores, specifically Intelligence? There was a brilliantgameologists thread a while back, but it's been removed since then.

In response to your first query, the only thing I can think of is the Action Points variant (Link). Basically it allows you to roll 1d6 (increasing to 3d6 by level 15) and add the result to any d20 roll. Check out the SRD for all the info, there is too much to put up here.

There's a Stance in ToB that lets you take 11 on any d20 roll.

X stat to Y bonus(surprisingly tough to find, even with search) for the second.

If I'm correct(AFB right now) there's a feat, Devil's Favor, that lets you add a bonus to one roll per day.

I think the knight of the stars and the like out of BoED lets you get a +1 to any roll daily.

Surge of Fortune comes very close.

The result of the next attack roll, saving throw, skill check, ability check, or spell penetration check you attempt is treated as a natural 20, as long as it occurs within 1 round of the time you invoked this power.

Stone of Good Luck gives a +1 to Saves, Ability Checks, and Skill Checks.

Improvisation (SpC) gives a bonus to Attacks, Ability Checks, and Skill Checks.

My Optimized Races Compendium is a good place to start on the Int. Normally character don't solely optimize int past level 4-ish. Other things like skill points or saves or spell DCs end up being easier to specifically optimize. If you post over on my BG thread (no necromancy rules) I can help you mor

[Thurbane]

There's the human only feat in RoD called Heroic Destiny that allows you to add +1d6 to any d20 roll, 1/day.

[dextercorvia]

Which reminds me, the 9th level spell in the Destiny domain allows you to reroll all (d20) rolls over the duration. I can't remember the name, but IIRC, it is persistable.

Int: Grey Elf (+2 Int, +2 Dex, -2 Con, -2 Str)

Feats: Faerie Mysteries Initiate (Int to HP instead of Con), Keen INtellect (Int to Will Saves and most of the good Wis-based skills), Lightning Reflexes (Int to Reflex Saves), Knowledge Devotion (make INt-based Knowledge checks for bonuses to hit and damage).

Classes: Factotum (depending how much you take of it (at least 3 levels recommended to grab Int to Init and all Str/Dex checks), Int to all sorts of stuff. At 16 you get it permanently to AC, but you can get it to hit, damage, saves, and AC each for 1 inspiration point much earlier in the class).
Swashbuckler 3 gives Int to damage
Warblade uses Int for random combatty things here and there (crit confirmation, resist trip, etc.)
