Hello: I was wondering if there is a way to add a blur effect to a portion of a map my players are on. It's Gibbet Crossing in Phandelver and Below: The Shattered Obelisk, and a few rooms have had a permanent Blur spell cast on them. I thought it would be neat when they arrived there so see the map blurry and try to figure it out rather than me just telling them. Thank you!
