Domain Expansion: The user can expand a barrier which is imbued with their cursed
technique. The inside is a sort of metaphysical space. Domains have a sure-hit effect, an
attack that's guaranteed to hit the target. Through a series of mystic incantations and hand movement, you may form reality into a black bubble, creating a demiplane considered as your domain. Each creature within 30 feet must
make a wisdom saving throw, being pulled into the domain on a failure. The domain occupies a 120-foot radius sphere. Any creature besides yourself cannot teleport out of the domain.
Inside the domain, the enemy is trapped in their last moment of life. To them,
everything slows to an endless instant - they can think, they can feel fear,
but they cannot move. The user, however, moves freely, deciding exactly how
that "final moment"' ends.
The inside of a domain looks like vast white void or ashen-gray world with everything frozen mid-motion
crumbling rocks, falling dust, even sparks in the air, all suspended.
A giant, cracked clock face beneath the user's feet, with the hands stuck at
the exact same position (like the time of their opponent's death is already
decided). The air looks distorted, like glass about to shatter, giving a sense of stretched
reality.
