With 1 minute of work, you can modify a serum of healing so that when it’s consumed by or administered to a specific creature, it restores a number of additional Hit Points equal to the serum’s item level. You can modify a number of serums this way each day equal to your Intelligence modifier. These modifications expire after 24 hours, returning the serum to its normal function.
