Question: Are purview lasers now restricted to the Inue with their 6-dot boon?

Nope. If you check out the "Ready, Aim, Fire!" sidebar on page 10 of the supplement, right next to said six-dot boon, you'll see that it suggests using purview lasers for everybody and offers a suggestion for how to implement doing so alongside Inue Scions using Qipanniq.

We use "purview lasers" in our games, but they aren't a feature of the original system, and as we have frequently noted, the pantheon PDFs are designed to be compatible with the original system for those who might still be using it.
