Iron Flesh Sheathe (3.5e Maneuver)

''Spears poked out of of every visible patch of his skin, transforming the warblade into a walking armory. He didn't even seem phased by it.''

When a creature strikes you with a piercing or slashing weapon, it becomes stuck inside your body. The creature must succeed on a strength check against DC 19 + Str mod, or the weapon cannot be removed from your body. You can pull out a weapon embedded in your body with the same action as drawing a weapon, and it has a +5 morale bonus on attack and damage as long as you wield it. The bonus lasts until you drop the weapon or exit the stance.

Natural weapons cannot be entrapped, but they do get slowed down and disrupted in your flesh. If they do not succeed on the strength check, they provoke an attack of opportunity as they struggle to pull back.
