I'm actually not very sure how Cerydra works. Suppose Anaxa triggers coup de main with his first skill, does the crit and res pen buff apply to:
>The skill repeated by Anaxa's talent, the skill repeated by Cerydra and the skill repeated by Anaxa's talent off of the skill repeated by Cerydra
>The skill repeated by Cerydra and the skill repeated by Anaxa's talent off of the skill repeated by Cerydra
or just
>The skill repeated by Cerydra
