Agile Half-plate

This style of Half-plate is specially crafted in a manner that allows extra maneuverability for some physical activities.

Benefit: The armor check penalty for Climb checks and jump checks is only –4 (masterwork and mithral versions of this armor reduce this penalty as well as the normal penalty). In addition, unlike most heavy armors, the wearer can still Run at quadruple speed instead of triple speed.
