This is a copy and paste directly from the "Tools of Two Trades" in Dragon 402:

"Benefit: You gain a +1 feat bonus to weapon attack rolls you make with any one-handed melee weapon and a +1 feat bonus to implement attack rolls you make with holy symbols. These bonuses increase to +2 at 11th level and +3 at 21st level.
In addition, while you use a shield, your allies gain a +1 shield bonus to AC."
