You keep saying the codex implies it’s a ritual, but I’ve already explained to you and Elm that it doesn’t. It’s ambiguous.
And it’s not baseless to say that it’s under his own power.
'Whispered rumors have persisted of planets snuffed out through intricate Sith rituals or by way of deadly, arcane machines--such as the device Revan sought to employ on Yavin 4--but Ziost represents a clear display of the corrosive power of the dark side of the Force taken to its extreme.'
The text pretty clearly seperates Ziost's destruction from those caused by rituals or machines and suggests its the corrosive power of the dark side that caused it instead. At the very least it doesn't indicate a ritual at all.
I honestly don't get the point of this think. Rituals require already having the raw power required to power them as well as the mastery and affinity for the Force to use them. If the point was to say Vitiate can't just randomly use it in combat, that argument is pointless. Drain is already stated to be hard to use in combat for anyone. I think if Bane can get over that limitation, Vitiate can. No one in Star Wars has a presence in the Force comparable to an entire planet's population anyway.
