True Geas

You inscribe an unavoidable command onto the heart of a creature that can both hear and understand you within range, forcing a Wisdom saving throw; this command can compel a course of action or prevent some course of action or activity as decided by you. On a failed save the creature is charmed by you indefinitely. While thusly charmed the creature cannot violate the command on pain of death. If the command is violated, the creature dies outright.

You can issue any command you choose. If a suicidal command is issued the creature has advantage on the saving throw.

You can end the spell early by using an action to dismiss it. A remove curse cast at 9th level or a wish spell also ends it.
