You may speak into the machine a command. The length of the command is limited to one or two sentences. You then indicate up to twelve creatures which you can see and are within range of the machine. When activated, all the creatures must make a WIS saving throw.    On a failed save, it pursues the command you described to the best of its ability. The command may be sustained for the duration of the effect. If it is completed before the 24 hour duration ends, then the effect ends as soon as the command is completed.   On a successful save, the command is ignored.   When issuing the command to the machine, it must be worded in such a manner that makes it sound reasonable. For example, you may not ask a creature to stab itself, throw itself onto a spear, immolate oneself, etc., as this would immediately negate the effect of the machine.   The command you issue may also have specific parameters. For example, you may command that a guard gives its rifle to the first researcher they meet. If they do not meet a researcher in the 24 hour span, they will not perform the command.   If any creature under the effects of the machine are damaged, they are immediately taken out of the machine's effects.
