Tenser's Portmanteau of Frugality (Magic Case)

This moderately large, black leather traveling case contains a bewildering number of small instruments—tweezers, measuring beakers, small ceramic jars, and the like. It can be used to extract the greatest possible benefit from certain single-use magical items by partly diluting or admixing them. All potions, oils, dusts, incenses, glues, solvents, and Nolzur's marvelous pigments can be affected by Tenser's portmanteau.
For every two potions, applications of dust, or similar substances that are treated by the portmanteau, a third active dose or use can be extracted. Any such item may be affected only once by the power of the portmanteau. Single doses (a single potion, etc.) do not provide sufficient magic for treatment by the portmanteau.
The process of extracting the magic is not a simple task. The work takes 2d6 hours to complete. At the end of this time, the wizard must make an Intelligence check. If successful, the third dose is created. If failed, the third dose fails and only enough remains of the original materials for a single dose of the magical substance.
If Alamir's fundamental breakdown is cast during the process, the wizard gains a +2 to his Intelligence check. In this situation, the spell does not consume the magical items on which it is cast.
Each use of the portmanteau consumes some of the special agents required for the process. When discovered, the case holds enough materials to attempt 4d10 duplications.
