Psychic Inquisitor. The Plague Knight is always under the effect of a detect thoughts spell and it does not need to maintain concentration. If dispel magic is cast on the Plague Knight, the effect is negated for one hour.

Foul Smite. When the Plague Knight hits a creature with a melee weapon attack, it can expend one spell slot to deal necrotic damage to the target, in addition to the weapon’s damage. The extra damage is 2d8 for a 1st-level spell slot, plus 1d8 for each spell level higher than 1st.

Spellcasting. The Plague Knight is a 9th-level spellcaster. Its spellcasting ability is Charisma (spell save DC 15, +7 to hit with spell attacks). The Plague Knight has the following paladin spells prepared:

1st level (3 slots): dissonant whispers, cause fear, wrathful smite

Denounce the Profane (3/day). As an action, all creatures of the Plague Knight’s choice within 60 feet make a DC 16 INT save. On a failed save, the creature is deafened, cannot speak, and has disadvantage on all d20 rolls that use Wisdom for 1 minute. On a successful save, the creature is only deafened. Casting remove curse ends these effects.
