Buffing my Beguiler as a bard

[ReD_Exorcist]

I have a beguiler in my party and currently I am playing a bard. I took the Draconic Aura to give him spell penetration. Currently I am a lvl 10 Bard Silverbrow Human. Any spells or feats or items that can help me buff him? I have eagles splendor

Beguilers are Int based — you need Fox's Cunning.

There is a lot of overlap between Beguilers and Bards, also there are different types of Beguiler. If his secondary focus is Cha then Eagle's Splendour will help, if he's Dex based then you need Cat's Grace.
The best Beguilers have Wisdom as their secondary stat however — for which you need Owl's Wisdom — so it all really depends upon his character; this shouldn't be important at low level though.

In any event he needs a Headband of Intellect since that will give him bonus spells as well as boosting his DCs.
