My concern about the owl vital attack patterns is that they are only
matched once during owl analysis. So I would only add patterns which are
more urgent, such as a serious threat, or destroying two eyes at same
time to them. This pattern could be formed after several steps in owl
analysis. In my test, the owl attack pattern still gets tried both in my
test case and in your test case.
