Magic Item to Boost Caster Level Checks...Abjurations v. Dragons

[Brace Cormaeril]

Are there any magic items that increase one's caster level checks?

Also, when a dragon enters my Anti-life Shell, I then make the CL check, right?
Thanks!

Anything that improves your caster level at the time you cast the spell. For example, a bead of karma used while casting greater dispel magic will increase your caster level on all dispel checks (still restricted to a maximum though).

That would be an SR penetration check (which is mostly a caster level check...). If you're an Arcane Spellcaster, an approprietly-aligned Robe of the Archmagi can help.

ioun stone in the DMG gives +1 CL and a ring in CA gives +1 CL
