You are permitted one object per permanent Gnosis point you have.
The rite is for mundane items like backpacks and trousers. If you have a talen or fetish (magical object with a spirit bound into it), that will come with you automatically - it doesn't count towards your quota of items.
Really big objects might "cost" more than 1 Gnosis.
You'll lose Wisdom points for binding "inappropriate" items to you (examples are gameboys, chainsaws and wristwatches). This rule does not apply to Glass Walkers or Bone Gnawers.
GM and player must discuss what happens to the object in different forms. Examples are a backpack's straps magically stretch to fit your Crinos form, or a knife becomes a tattoo when you are in Hispo form.
