Yes, Firewine Bridge and dungeon are made wild magic areas to make the suit their story:

It's something that should happen. If you're asking if it should be for both Arcane and Divine: I don't know, I just used the exact copy of wild magic area resource made by devs.

My mod adds tiny rooms for the turrets. NTotSC adds a different entrance to its new area, I checked that when working on the mod. However, my mod does not make NTotSC areas wild magic areas.
