The Black Banner Above

The caster enchants their warbanner, planting it into the ground and expanding its size. The banner creates a 50-foot radius sphere around it, stemming from the end of the banner placed in the ground. The top of the sphere is 50 feet high, and in this area, a great feeling of dread washes over creatures hostile to the caster. These creatures are magically poisoned by the banner, and gain disadvantage on saving throws against the caster or their allies. Additionally, inside of the banner’s jurisdiction, hostile creatures hear whispers and voices of fear and regret. A hostile creature must succeed on a Wisdom saving throw against the caster’s spell save DC, with the paranoia eating away at them and dealing 4d4 necrotic damage per turn on a failed save, and 1d4 on a successful one. The banner sheds magical dim light inside of the effective range, and hostile creatures can only see 10 feet in any direction around them unless they possess a source of magical light.
