[tlhIngan Hol] Does rIntaH require a sentient being ?

Assume qeylIS writes an oath, which when heard, turns a coward to a warrior. And this effect of the oath cannot be undone. It is a magical oath of sorts. Could the former coward say: muchoH rIntaH 'ip mu'mey the words of the oath changed me Or is the rIntaH to be used, only when the one who {rIntaH}s is someone sentient ? ~ changan qIj
