How long until guardian scrolls and such come out?

Right, but iirc, they remove the Boom part of those scroll methods. That could mean protection scrolls might not be brought back. (Hopefully we'd have at least one more round of availability so we that we can continue to use older scrolls we still carry.)

Enhancement scrolls still boom though, and the anni scrolls will most likely still boom for those that stock up on them. I don't think they removed booming on scrolls entirely they just lowered the rate by a lot, but could be wrong.
