As highlighted in the slime power/numbers compliant thread, some people have no opportunity to train vs animals without suffering from wounds. I suggest implementing animal/monster dummies that you could initiate a spar against. They will be static, but at least you will have an idea about your abilities and how much would they be able to hit you.
So, for the construction you would need some straw and the dried animal hide, which will determine what kind of dummie you would get.
