Equivalent scroll of food detection

The spellbook of food detection allows you to learn the detect food spell. Casting this spell has the same effect as the scroll of food detection, revealing the location of all comestibles on the level, on the ground and even in monster inventories. If cast at skilled or expert, you will also acquire the food appraisal intrinsic. This spell is the only one in NetHack that does not cause spell hunger at all, especially important given its function. It can be used to train divination spells.

Strategy

The obvious use is if you are short on food you can cast this spell to find food on the level. This can be a real lifesaver in a fix, but beware, it will also display tainted and poisoned corpses and corpses that can cause petrification or other harmful effects. As you go deeper into the dungeons, food becomes more abundant, and this spell loses much of its base value. However, once you become skilled or expert in divination, you can use it as a faux-permenant food appraisal intrinsic by recasting every time you get a warning, as it drains very little energy.
