When cast on a victim in sight, human or non-human, the target must make a
CON saving throw.
If this fails, the speaker of the spell has the option to give the target a command, using a text in melody (common, Elvish, Dwarvish), of his choice, and the victim must obey it, regardless of whether an obvious death is foreseen as a result, but is not directly commanded. For example, the command "Jump off a cliff" can only be carried out if there is a chance of survival, such as water at the bottom of the cliff. The command "plunge a sword into your heart", for example, cannot be executed because it is almost impossible to survive.
The spell ends as soon as the target has performed its task. There are no side effects after the spell ends.
If the target succeeds in his CON saving throw, he is immune to enchantments until the end of the battle. If the spell is not used in combat, the victim is immune for the next 5 minutes.
If the caster is interrupted while speaking the command, for example by an attack, he cannot speak the same command again on the same target.
