So, I'm Looking to switch from 5e to pathfinder 2nd edition. I've read most of the rules and going through the class options at the moment and I've been scratching my head over this one for a day now.
The Leaf Druid has access to the order spell Impaling Briars (https://2e.aonprd.com/Spells.aspx?ID=475).
One of the effect of the spell is to have a Wall of Thorns spell affect the area or the Impaling Briars. Since Impaling Briars is a focus spell and focus spell are automatically heightened, would the Wall of Thorns effect also be heightened or would it remain level 3?
