I have a idea for make better the utilization of potion: Creating a "graal" and this are selling in any NPC. How it's work?

A tiny/medium/large purple(or red) Graal:
Regen (1% of graal) of your MP(or HP) per second until (100% of graal). potions with the color of graal loss 50% of efetivity.

Cost: 20x(vial's size)

The size's of graal are 20X of the vial's size too, and incorpore's like food (only one graal are allowed to use per graal). With this no more problems with forget to potting and utilize's your mouse with a better way.
