495 Kind Intentions

[Kind Intentions] was an incredibly complex bit of Unholy Magic that would keep hostile beings and magic out of an area. It judged their nature, and if they were deemed unworthy, inherently hostile or traitorous, they would be prohibited from entry or blocked from hostile actions.
