As two actions, you can create this vial of pink swirling gas. As an action, a creature can throw the vial at a point within 5 meters, shattering it on impact. Each creature in a sphere centered on that point must make a Will saving throw.
On a failure, a creature becomes mellow and relaxed, indifferent to all creatures it is hostile towards. This indifference ends if the target is attacked or harmed by a spell or if it witnesses any of its friends being harmed. When the effect ends, the creature becomes hostile again, unless the GM rules otherwise.
