I could be wrong, but now it seems like Champion of the Gods is a bit too strong for 2nd level. I'll post it, and see what people think.

Also, here's one whose level I can't place. I'm thinking 2nd level.

Warded Shield

School Abjuration
Level Paladin 2
Casting Time: 1 Swift Action
Components: V, S, F (any wielded shield)
Range: Personal
Target: You
Duration: 1 minute/level

You layer magical wards onto your shield, enabling it to add additional protection against magical attacks. You can add your shield bonus plus an extra +1 per four levels up to +5 to your AC vs magical ray effects, and saving throws.
