From d20pfsrd.com, the Witch gets the following Hex:
Slumber (Su): A witch can cause a creature within 30 feet to fall into a deep, magical sleep, as per the spell sleep. The creature receives a Will save to negate the effect. If the save fails, the creature falls asleep for a number of rounds equal to the witch’s level. This hex can affect a creature of any HD. The creature will not wake due to noise or light, but others can rouse it with a standard action. This hex ends immediately if the creature takes damage. Whether or not the save is successful, a creature cannot be the target of this hex again for 1 day.
Now, my question is whether that would count as a Mind-Affecting Compulsion (as the Sleep
spell does)? Mainly, I want to know if Protection from Good
/Evil
/Whatever would be enough to counter it.
