From the blue notes of Pearl Abyss: "...And among the treasure items, adventurers wanted and made the most, and we were looking for a direction for a lower version of the Infinite Potions..."

How about a potion that charges it after 100 chuggs of HP, and when the charge is 100% complete, you can use it to heal yourself for an amount of like 1000 or maybe even 1500. This is kind of like an Infinite Whale Potion but with a requirement of 'charging it' by consuming either regular HP potions or taking a sip of your amazing Infinite Health Potion.
