In all seriousness, burning through two detect materials for enner is rather counterproductive for the late game. Of course if you've got plenty and don't intend to go for the knight or high priest ending it's fine, but under normal circumstances you rarely have that many. For me, a proper run for Elpuri takes a minimum of 3 scrolls (GC5, GC7, GC9), more if something goes wrong on the said levels. Going up to Oree needs anything between 0-4 depending on gear quality, meaning in the worst case you'll be looking at blowing 7 or more of them for a high priest run.
IMO enner just doesn't need the map detection, there's plenty of opportunities later to use that scroll.
