In this section of Lucky's Lore i'm going to explain how i obtain the Essence without Hurting people and why some essences are more prominent than others.
Featuring my friend  Pawpy Nebulos

Basically;
1.- Each specie share the same Essence. A traveling on subway let me fill flash of "Human Essence" needed for almost all potions.
2.- Rare species make collecting Essence more harder, depending how rare the creatures are the potion migth be more Expensive.
3.- Extracting Essence doesn't damage people if is used responsably.
4.- Extracting Essence from someone until it gey dry would remove their blank.
5.- By the point someone got their Essence drained fully obtain a "Specific Essence" for that person!
