Expeditious Alchemy

You can produce alchemical items much more quickly than normal.
As part of a short or long rest, you can produce a single unstable alchemical item. An unstable alchemical item functions in all ways like its normal counterpart, except it remains potent for only 24 hours. Items crafted in this way cost no gold pieces, but their volatile nature prevents you from carrying more than one at a time. Crafting a new unstable alchemical item immediately renders the previous one inert. You must be proficient with and have access to a set of alchemist’s tools to benefit from this feat.
