Aurelian Binder

Nullstone Adept. While wearing its nullstone harness, the binder is unaffected by arcane spells of 1st level or lower unless it wishes to be affected. This protection requires specialized training and conditioning; other creatures wearing the binder’s gear don’t gain this benefit.

Spellbreaker. When a creature the binder can see within 60 feet casts an arcane spell, that creature has Disadvantage on the next Constitution saving throw it makes to maintain Concentration before the end of its next turn.

Multiattack. The binder makes two Holy Chains attacks.

Holy Chains. Melee or Ranged Attack Roll: +5, reach 10 ft. or range 30/120 ft. Hit: 8 (1d10 + 3) slashing damage plus 7 (2d6) radiant damage. If the target is Large or smaller, its Speed becomes 0 until the start of the binder’s next turn.

Silencing Pulse. (Recharge 5–6) Nullstone energy ripples outward. Each creature of the binder’s choice within 15 feet must make a DC 15 Constitution saving throw. On a failed save, a creature takes 13 (3d8) force damage and can’t take Reactions until the end of its next turn. On a successful save, it takes half as much damage.

Seal the Heretic. One creature the binder can see within 30 feet that is concentrating on a spell takes 5 (1d10) radiant damage.
