Unparryable

It is your fault, and I believe arises either from an ill-judged idea of smoothing matters to me — as if I were not behind the curtain — or a general reluctance to allow that any danger is near, until it is almost unparryable.

It sliced through shields and swords vainly raised in an attempt to parry an unparryable blow as if it were light, yet when it struck, it was hard as forged iron.
