Craft Robe Patch

You convert an obedient creature or common item, of 10GP value or less, into a patch that is affixed to the Robe.

To cast the base spell requires 1 hour with the Robe the Patch will be affixed to. After this, the caster must continue maintaining concentration while touching the creature or item until it is converted into a Patch. The Patch Conversion process takes 36 seconds and 1SP worth of golden thread(which is consumed) for every pound that the item or creature weighs, plus 1GP for every patch the robe already has affixed to it. A robe cannot hold more than 28 patches, and attempting to cast the spell on a full robe will fail before any golden thread is consumed.
Once becoming a patch, the creature or item is no longer affected by time, but a dead creature will not experience any sort of extension on the time in which it may be resurrected.

Creatures without a specified value may have their value determined by the DM. Animals that can be summoned via Find Familar can be assumed to have a value of 10GP, provided you can obtain one that is obedient. Use the "Mounts and Other Animals" section to estimate the value of other creatures that might not be listed.

At Higher Levels. When casting this spell at 2nd level or higher, you may include a number of creatures/items equal to the spell slot cast from, though any individual patch may only contain a single type of creature/item.
The total value of the creature(s) or item(s) being converted into a patch may have a value up to 50GP, with an additional 50GP for each slot above 2nd, and an additional 100GP for each slot above 5th. (Maximum of 600GP at 9th level)
In addition, 6th-9th level slots can be used to create a patch from a structure, such as an iron door, or an item of an uncommon rarity. Pits and Windows will have their structure filled in with the surrounding material when they are converted to a patch, and are treated as weighing the same as the material they become filled with.
