Void Domination

Effect: You reach into the mind of a creature you can see within range and flood their consciousness with the suffocating void, twisting their will to your control. The target must make a Wisdom saving throw. On a failed save, the target is charmed by you and falls under your complete control for the duration. While charmed, the target obeys your spoken commands to the best of its ability. The target does not realize they are under the influence of the Void, and the control is so complete that they are unaware of your manipulation.

The target has advantage on saving throws to resist this effect if it is threatened or attacked by you or your allies. However, even if the creature is not actively threatened, the oppressive force of the Void remains potent enough to silence their thoughts, leaving them in a state of confusion when not acting upon your commands. The target is still capable of basic self-preservation, such as avoiding immediate hazards, but cannot take actions against your will.

If the target succeeds on the saving throw, it cannot be affected by this spell for the next 24 hours.

At Higher Levels: When you cast this spell using a spell slot of 9th level, the duration increases to 230 days.

Lore & Flavor:

Void Domination is one of the most feared and forbidden spells in existence. Those who wield this magic are able to usurp the very minds of others, drowning their consciousness in the consuming darkness of the Void. It is said that casting this spell is akin to making a pact with the Void itself, as the caster’s mind is often left scarred by the process, experiencing fleeting glimpses of madness. This spell is favored by dark sorcerers, ancient warlocks, and beings who wish to exert their dominance over others through sheer willpower. The caster does not just bend a creature's mind to their will—they twist and tear at the essence of the creature's soul.
