Creation
You pull wisps of shadow material from the Shadowfell to create an object within range. It is either an object of vegetable matter (soft goods, rope, wood, and the like) or mineral matter (stone, crystal, metal, and the like). The object must be no larger than a 5-foot Cube, and the object must be of a form and material that you have seen.
The spell's duration depends on the object's material, as shown in the Materials table. If the object is composed of multiple materials, use the shortest duration. Using any object created by this spell as another spell's Material component causes the other spell to fail.
Material Duration
Vegetable matter 24 hours
Stone or crystal 12 hours
Precious metals 1 hour
Gems 10 minutes
Adamantine or mithral 1 minute.
Using a Higher-Level Spell Slot. The Cube increases by 5 feet for each spell slot level above 5.
Creation 5e 2024 vs. 2014 edition differences
The 2024 version specifies a 30-foot range, whereas the 2014 version has no range specified. The 2024 version clarifies the object can be of vegetable or mineral matter, with durations: vegetable matter 24 hours (vs. 1 day), stone/crystal 12 hours (vs. 12 hours), metals 1 hour (vs. 1 hour), gems 10 minutes (vs. 10 minutes). The 2014 version's duration for vegetable matter is 1 day, but the 2024 version explicitly states 24 hours. The 2024 version simplifies the material durations, and the range is explicitly defined.
