Thank you for doing testing on this Xilk. I went and searched the Japanese forums for their Japanese version of Camates post and translated it to find that Camate didn't translate wrong. Camate clearly says offense while from the translator Oriole specifies attack. How Familiar does it is beyond me and I will try to do some testing myself to see if I can figure it out.

Heres both copies of text for anyone else interested.

The strength of the stoneskin effect will vary depending on the pet. The idea is that Familiar will increase the pet’s offensive capabilities, while the new 2-hour ability will enhance the master’s defensive capability.

獣使いの2Hアビリティは、使い魔がペットの攻撃面の底上げなのに対し、マスターの防御面を大幅に引き上げるという方向性で考えています。
