You can use transformation magic to change a target object into another object.  You must make a successful Scrivening check to correctly change the target.   Magical or inkforged objects get to make a Resist check to resist the change.

​

If you want to change the size of a target then you must first use Scale to modify the spell to work on a target of that size.  Then you add +2 Spirit for each difference in size rank between what it is and what you want it to be.  This can be done by itself, or as part of transforming the target into a different creature.   This is also how changing the material quality of an object works.  You can modify the workmanship or material strength of an object by paying the difference measured by the Intensity mod.

​

Note that transformed objects do not gain all the mechanical or magical traits of their new form unless you put Spirit into the Intensity modifier to include such aspects.  The amount you spend determines the number of mechanisms and traits you give to the transformed target.  This is provided that you are familiar enough with the new form to transform everything correctly. 

This spell costs 3 Spirit to cast.
