Magic Codpiece clarification

[WhatBall]

Howdy. The rules for this card state:

injury rolls against this player cannot be modified or re-rolled by anything including (but not limited to) Dirty Player, Mighty Blow, Piling On, and Stunty.

By the letter of the wording, this means Piling On and Claw can be used on the Armour roll, but not the Injury roll. Is this the intent or is the card meant to negate Armour RRs with PO and Claw AV reduction as well.

Thanks.

It says Injury rolls, it doesn't say anything about Armour Rolls, so skills that affect AV can still be used.
