After a week of reading his book, and attempting to create potions, Fip manages to create 1 potion of healing. The first potion that Fip attempted to create was accidently lost when on the final day of the week Scree apparently returned to having control of Erik's body and barged in on Fip. He was so startled that he accidentally poured to much solution into the vial ruining the potion.
Out of character
It is now 18 Yurthgreen, Scree is back. You brewed 1 potion and lost mats for the other potion that was ruined.
You receive next letter from home on 1st of Fleurgreen, which is total of 18 days from the start of downtime (11 Yurthgreen). So you won't see that one till after the Witchlight sessions are over.
