That thing he sent you's page

If I have the Advanced Players Guide and not Ultimate Equipment, can I say get a weapon with the furious ability? Sorry if this is a stupid question.

With the opening up of ifrits and undines to pathfinder society I have some questions about these two abilities.

Shadows Chill states that one point of sneak attack damage per die is cold damage does that mean it is no longer precision damage? If so is it multiplied on a critical hit?

Elemental strike says as a swift action for one round your weapons deal 1 additional point of energy damage depending on type, does this activate fire forged steel. If not would the ifrit brazen arms ability activate fire forged steel?

A steelblood bloodrager gains Armor Training that stacks with fighter Armor Training. Does this allow a steelblood bloodrager to take advanced armor training, and if not would taking 3 levels of fighter allow a steelblood access to advanced armor training ?
