Stellar Drift Dust

Effect: Silver dust from the deep Astral. When scattered in a 20-foot radius, creates temporary Ethereal permeability for 10 minutes. During this time: incorporeal Ethereal entities can enter the Material without Gate Keeper assessment; Material creatures can see into the adjacent Ethereal; magical effects interacting with the Ethereal have their range doubled while operating from within the dusted area.
Uses: One use. Found 1d3 pinches at a time.
