Cleanrot Knight (Spear Variant)

Indomitable (2/Day). The champion rerolls a failed saving throw.

Swift. The Cleanrot Knight does not provoke opportunity attacks when they move if they have already taken an Action that round.

Impale. If the Cleanrot Knight moves at least 15ft straight forward towards a target and then hits it with a Spear attack on the same turn, the target takes an additional 14 (4d6) necrotic damage. If the target is a creature, it must succeed on a DC 18 Constitution saving throw or suffer 1 level of exhaustion. 

Multiattack. The champion makes three attacks, which can be any combination of Spear and Sword attacks.

Sword. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 14 (2d8 + 5) slashing damage.

Spear. Ranged Weapon Attack: +10 to hit, reach 10 ft., one target. Hit: 12 (2d6 + 5) piercing damage.

Sacred Phalanx (Recharge 5-6). The knight drags their spear across the ground before slashing upwards, conjuring a wave of glowing golden spears in a 30ft cone in front of them. All creatures within the area must succeed on a DC 18 Dexterity saving throw, taking 45 (10d8) radiant damage on a failed save, or half as much on a successful one.

Parry. The Cleanrot Knight adds 5 to their AC against one weapon attack that would hit them. To do so, the Cleanrot knight must be wielding their sword and see the attacker.
