Command

This spell enables the cleric to issue a command of a single word. 

The command must be uttered in a language which the spell recipient is able to understand. The individual will obey to the best of his/her/its ability only so long as the command is absolutely clear and unequivocal, i.e. "Suicide!" could be a noun, so the creature would ignore the command. A command to "Die!" would cause the recipient to fall in a faint or cataleptic state for 1 round, but thereafter the creature would be alive and well. 

Typical command words are: back, halt, flee, run, stop, fall, fly, go, leave, surrender, sleep, rest, etc. 

Undead are not affected by a command. Creatures with Intelligence of 13 or more, and creatures with 6 or more hit dice (or experience levels) are entitled to a saving throw versus magic. (Creatures with 13 or higher Intelligence and 6 hit dice/levels do not get 2 saving throws!)
