You cast upon yourself a dormant non-revealing spell usually when in a vulnerable state like resting. When your vulnerable (resting) space is penetrated, or you are touched you trigger a green aura centered on your target, additionally, the target is exhausted. The glowing aura is only visible to the caster, unless the caster speaks a verbal command to make it visible to the target and/or party. The spell lasts for the duration or until the caster dispels it, regardless of spell level the exhaustion will only last for a maximum of 3 hours.

• Green Aura - Lasts for duration of spell per caster level
• Exhaustion - Lasts ONLY for a maximum of 3 hours regardless of caster spell level

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the green aura increases in duration by 1 day for each slot level above 1st. However, the exhaustion does not extend beyond its duration regardless of the caster spell level.
