Reaching with his hand in his shadow, Zaroth got a bottle of water and a handful of salt and sugar. Then he mixed them and forced himself to drink the cocktail he had created.
Why had he bothered to do such a thing? Even if Lily had helped him immensely by using Shifter to recover most of his mana, his body was exhausted, not to mention he had given Midnight a portion of his blood. The combination he had just drunk helped stabilize his condition a little. It was by no means healing potion or anything of the sort, but it was going to do the trick.
And as for why Zaroth pretty much never used any potions was because he had been taught in the academy that pretty much all of them had very significant drawbacks for using them, so he never relied on them.
