Concrete placer is a combat skill, created by an unknown hero with even less common sense than is usual for adventurers. It involves pouring quick-set concrete over the hands, legs or other appendages of the hero, coating them entirely. This may seem like an incredibly stupid thing to do (even by a hero's standards) but it actually helps to enhance their next attack by giving it some extra oomph. Unfortunately they are then left covered in concrete. True mastery of Concrete Placing requires the hero to be able to remove the concrete from themselves quickly and efficiently, but due to the nature of the skill, they rarely get the chance to practice it more than once.
Combined “concrete placer” with one of my other skills against the Great Caesar's Ghost, knocking both it and myself flat. Wow!
