“I create potions which bolster your strength as ruler alicorns. Yet you torment me with teasing about the size of my breasts,” - Chryaslis.
“How can we not? You’re just so cute when you’re full of potion and need assistance for every little thing,” - Celestia.
“Just take your brew and go so I can return to my hut,” - Chrysalis.

In order to creation very specific potions a more personal touch is required. Unfortunately does mean limiting the crafter’s mobility but I’m sure the alicorn sisters take good care of Chrysalis in her immobile state.
