Furthermore, the white mist was an evolving talent, initially only capable of blocking sunlight and obscuring the vision of living beings. But as its talent level increased, the mist became extraordinary.
The most basic way it evolved was to fill the mist with undead power, so when the mist appeared, the undead energy within would rapidly heal the skeletons enshrouded in it. Simply put, it provided shelter for the weaker skeletons, and this is why high-ranking undead creatures often have many lower-ranking undead following them.
Besides infusing the mist with undead power, it could also be mixed with toxins, curses, or a range of negative energies that weakened other beings before they even considered entering the mist to engage the skeletons in close combat.
Moreover, many high-level undead tailored their mist based on their surroundings or let the mist adapt to unique environments on its own.
