The recent version 3.25 update to Clash of Clans has a line item that says:
Heroes recover health faster thanks to the Alchemists' new sleep potion
When I look in my Spell Factory after the update, I don't see any such potion - and sources I've checked online don't have any information on it. Is this just a cute "canon" way of explaining the patch detail, or is the sleep potion a real thing you can purchase/create? Also, what is the new rate of health regen?
