For some reason, I can cast insect swarm and detect order when I don't have the fetish as Nightreaver.

Within the Tree of Ages
You are standing within an enormous hollow of the magnificent Tree of
Ages. Here, the massive tree opens up so broadly it appears as a massive
cave, save made of gnarled wood instead of stone. This is the last
remaining life from the Age of Thar'Eris, the ancient time of Thera
prior to the rise of civilization. Preserved by ancient gods and forces
of nature, the tree has opened its heart once again to offer refuge
to mortal servants that will return her again to her days of glory.
In the center of the tree a massive totem has been formed of the wood
itself, which shimmers with the essence of the Primeval Spirit.

On the north end of the hollow, you also see a huge piece of curled
bark affixed with the tree's golden sap. On it is a decree of commandments
scrawled in an ancient script.


A massive totem depicting ancient spirits has been carved here.
A pit of primordial ooze bubbles here.
A flickering spirit-being of pure energy inhabits the totem.
(White Aura) A tattooed wilder-elf woman crouches here, uttering ancient mantras.

The Primeval Spirit says 'The Blood Tribunal guards our item of power.'

You cannot find the Cabal Power within you.


Working as intended? Or bugg?

Due to the way cast is written, Insect Swarm will not fail when your cabal item is downed unless you give it a target. Had you specified a target, the spell would've balked at you.

Detect Order does not require your cabal item and being not very useful in PK I'm fine with that. Someone on Team Outlander is welcome to overrule me in the future on that one though.
