Nature Incarnate clarifies that when a Spirit does stuff with Presence, it refers to that Spirit’s Presence unless otherwise specified.
This is
sort of a change from the previous default
(the previous default wasn't consistent – e.g., Growth choices never bothered to specify that you were Adding your own Presence), but it only impacts two older items:
Draw Towards a Consuming Void (which gets an updated version in Nature Incarnate) and Finder of Paths Unseen (which can definitely move Presence from any Spirit, but reprinting the Spirit Panel and 4 Uniques in NI would be somewhat prohibitive, so it's getting this erratum).
