As an action, you provide succor to an ailing creature that you can touch, masking its suffering for the duration.

The creature no longer feels any physical pain or discomfort.

A creature can use an action to determine why it suddenly feels no pain, making a skill check using Insight (Intelligence) against your spell save Difficulty. If it succeeds, it becomes aware of the illusion and is immune to this spell for the next 24 hours.
