I may as well contribute to the tip giving.

There is a pair of enemies that you often encounter in Ipsen's Castle. The pair consists of a gargoyle and something else the name of which I forget. The gargoyle can be killed before coming to life by using a Soft. Alternatively, concentrate your efforts on the other [nameless] enemy. When he's gone, the gargoyle automatically goes with him if he's still in a Petrified state.
