Power Word Plague

8th-Level Necromancy

Casting Time: 1 action
Range: 60 feet
Components: V, M (a vial containing diseased skin)
Duration: Instantaneous

You speak a word of power, infecting a creature within range that can see and hear you with a virulent disease. If the target has 150 hit points or fewer, it contracts the disease. In addition, choose a number of creatures equal to your spellcasting ability modifier within 30 feet of the target. Each of those creatures must succeed on a Constitution saving throw or also contract the disease. These secondary targets can have any hit point total.

While diseased, a target suffers the following effects:

• At the start of each of its turns, the target’s hit point maximum decreases by 20.
• The target can’t regain hit points, except by magical spells higher than 5th level.
• The target’s speed is halved. The disease ends on a creature when the creature is reduced to 0 hit points.

The disease can also be ended by a greater restoration, heal, or wish spell.
