Shaman Amulet of Spirits and Early Access to Spirit Abilities

[FingersCrossed]

Looking through the amulet of spirits item for shamans which boosts your effective level for spirits powers, I was unsure whether this meant that you would get early access to greater and true spirit abilities for the amulet you are wearing.

Relevant text from the spirit ability:

Quote:

Spirit (Su): A shaman forms a mystical bond with the spirits of the world. She forms a lasting bond with a single spirit (see Spirits on page 37), which grants a number of abilities and defines many of her other class features.

At 1st level, a shaman gains the spirit ability granted by her chosen spirit. She adds the spells granted by that spirit to the list of spells that she can cast using spirit magic. She also adds the hexes possessed by that spirit to the list of hexes that she can use with the hex and wandering hex class features.

At 8th level, the shaman gains the abilities listed in the greater version of her selected spirit. At 16th level, the shaman gains the abilities listed for the true version of her selected spirit.

Relevent text from Amulet of Spirits:

Quote:

If a creature that already has the associated mystery or spirit wears the amulet, that wearer does not gain the abilities listed below; instead, the effective level of her mystery or spirit powers increases by 2.

You have to have a mystery or power before you can acquire an effective level increase for it.

(Just like if you were casting spells at +2 caster level, this wouldn't grant you access to more or higher level spells.)

Yeah, contrast that with the Robe of Arcane Heritage.

Quote:

The wearer treats her sorcerer level as 4 higher than normal for the purpose of determining what bloodline powers she can use and their effects.
