-The most obvious use for a scroll of food detection is to efficiently track down food if you are [[hungry]] and/or short on comestibles: remember that the scroll will display ''all'' comestibles, including [[corpse]]s that are [[tainted]] from age, [[poison]]ed, or otherwise harmful (e.g. [[petrification]] from a [[footrice]] corpse). Unless you have food appraisal from a blessed scroll), you will not get any warning before eating such a corpse, so do not chow down carelessly. The food appraisal intrinsic from the scroll is also useful to prevent breaking dietary [[conduct]]s; however, it will only warn you once before the intrinsic is lost and will need to be reapplied.
+The most obvious use for a scroll of food detection is to efficiently track down food if you are [[hungry]] and/or short on comestibles: remember that the scroll will display ''all'' comestibles, including [[corpse]]s that are [[tainted]] from age, [[poisonous]], or otherwise harmful (e.g. [[petrification]] from a [[footrice]] corpse). Unless you have food appraisal from a blessed scroll), you will not get any warning before eating such a corpse, so do not chow down carelessly. The food appraisal intrinsic from the scroll is also useful to prevent breaking dietary [[conduct]]s; however, it will only warn you once before the intrinsic is lost and will need to be reapplied.
 The potion-detecting capability of cursed and/or confused readings of the scroll have a niche application for finding useful potions, such as [[smoky potion]]s or a [[potion of gain level]], before a monster can grab it, or else kill a monster before they can use it; this functionality can generally be duplicated by other means, however. Once you learn the [[spell of detect food]] or reach a point where food is not much of a concern anymore, this scroll is a good candidate for [[blanking]]. The scroll may be of slightly more use for a hero attempting any food-based conducts, including [[vegan]] or even [[foodless]]; foodless heroes in particular may opt to use cursed scrolls and confused readings instead if they are not averse to maintaining liquid diets.
-{{upcoming|3.7.0|Per {{commit|39a7dc1c522d95b54e3238328dacef91c6ce8c47}}, monsters that do not pick up food items will not leave behind any comestibles besides their [[corpse]] as possible [[death drop]]s.
