Noticed that the Vindicare in Heed the Higher call has listed 2 talents that are not available for a player to aquire in game. They are the following

Armour of Contempt

Mental Fortress

Is this an error on the supplement or left out of the game error as my assassin would like to have them as well.

Thurumbar

Petition your GM for an elite advancement?

Thrumbar said:

Uhm... Both talents are absolutely available for players. They just may not be in your career path. Both are from the core rule book, and the following careers have access to them:

Armour of Contempt: Adept level 5, Adepta Sororitas level 3, Imperial Psyker level 8, Tech Priest level 6/7, Templar Calix

Mental Fortress: Adept level 8, Adepta Sororitas level 8, Imperial Psyker level 7/8, Tech Priest level 7, Tyrantine Shadow Agent

So you could ask your GM for elite advances on them, but you might want to do a little homework before you do. For example, Mental Fortress requires Strong Minded, and if you don't have that, you'd have to purchase that as well. In the link below in my signature, you'll find sheets that show all skills and talents (excluding the ones added in Radicals Handbook and Ascension) and who has them available and when.

A Vindicare Assassin is a whole 'nother level of assassin. They are Ascension level characters.
