Infiltrator Inquisitor

[mbauers]

So, infiltrator has the following replacement ability:

Guileful Lore:

Guileful Lore (Ex)

At 1st level, the infiltrator’s will is bent toward subterfuge and deception. She adds her Wisdom modifier on Bluff and Diplomacy skill checks in addition to the normal ability score modifiers.

This ability replaces monster lore.

Notice how it specifies "at first level". As far as I can tell, most archetypes list the level at which you receive the replacement ability. Now look at these abilities, also for the infiltrator:

Forbidden Lore:

Forbidden Lore (Ex)

While other inquisitors learned to track unbelievers, an infiltrator learns how to cast their spells. An infiltrator can cast spells of an alignment opposed to her or her deity (ignoring the restriction in the Chaotic, Evil, Good, and Lawful Spells class ability).

This ability replaces track.

Necessary Lies:

Necessary Lies (Su)

An infiltrator adds her class level on saving throws against abilities that detect lies or reveal or force the truth, such as detect lies and zone of truth.

This power replaces discern lies.

Since no level is specified, do I get both of these powers at first level? Or do I get them at the level in which I would normally get the powers that are being replaced?

[Elamdri]

You get them at the level in which you would normally get the powers that are being replaced.

[blackbloodtroll]

Usually, they spell it out.
Sometimes an archetype muddies the waters with when they give you replaced powers.
