[3.5] Pumping Sense Motive

[Thurbane]

Just a couple of questions about Sense Motive.

Looking for feats, items and class abilities to boost Sense Motive checks.
Apart from the standard uses of Sense Motive under the skill description, what feats and class abilities let you do other things with Sense Motive checks?

[Sith_Happens]

The 2nd level Setting Sun counter Baffling Defense (ToB) lets you use a Sense Motive check instead of AC against a single attack. If you aren't playing a martial adept, you can use it 1/encounter by buying a pair of Novice Setting Sun Slippers (3k).

[Andion Isurand]

The Master Astrologer PrC (Dragon 340 pg 36) grants a competence bonus to Sense Motive equal to your class level... and grants an alternate use for the skill that can increase spell checks to overcome SR and spell DCs against specific targets.

Also, in Complete Adventurer, there's rules for using Sense Motive to determine how dangerous an enemy is (CR-wise).
