You are skilled in combining your shield bash attack with an armed strike. When you use your shield in unison with a weapon, your training allows you to score telling blows with both.

Prerequisites: BAB 3+, base Dexterity 13+, Proficiency with a Shield

Benefit: Your shields damage improves to 1d8 for medium characters. If spikes are added to your shield, the critical threat range is increased to 19-20 and the damage type is bludgeoning and piercing. Once per turn when making a full-attack or using the charge action you may perform a shield bash. You do not lose your shield bonus to AC when doing so. After doing so you take a penalty until the start of your next turn. The penalty is applied to your shield bonus and it is equal to twice you shields armor check penalty.
