5-level Abjuration
You place a ward of protection at a point that you can see within
range. The point emanates an aura of peace in a 30-foot radius
sphere.
When a creature first enters the aura for the first time, they
must succeed on a Wisdom saving throw, or be unable to take
any action that can damage another creature whilst inside the
sphere. The caster knows of any creature that tried to resist the
saving throw, and any creature that succeeded.
Additionally, any creature that makes an attack roll against a
creature inside the sphere makes it at disadvantage.
