Question

What is "the hero pilored his craft with great skill " from active to passive

Answer 1

the sentence is written in active voice (where the subject (the hero) is performing the action (pilored his craft...)

so to change to passive voice, you want to re-write the sentence such that the subject is the action/task being performed *by* the subject

example:

I walked the dog ---> The dog was walked by me.

Try to apply this logic to your sentence.
