Blighted Sentinel

Hive Mind. The Blighted Sentinel is connected to the Blighted Hive Mind and can communicate telepathically with other Blighted creatures within range. If one Blighted creature is aware of a threat, all nearby Blighted creatures are also aware.

The Blighted Scourge. When the Blighted Sentinel hits with a natural weapon, the target must make a DC 17 Constitution saving throw. On a failure, they advance in the Blighted Scourge infection.

Reinforced Husk. The Blighted Sentinel's construct form gives it advantage on saving throws against being pushed or knocked prone.

Absorb Blighted Energy. If the Sentinel ends its turn in an area of blighted terrain or near another Blighted creature, it regains 10 hit points as it draws in surrounding blighted energy.

Multiattack. The Blighted Sentinel makes two Slam attacks.

Slam. Melee Weapon Attack: +11 to hit, reach 10 ft., one target. Hit: 22 (3d10 + 6) bludgeoning damage, and the target must make a DC 17 Constitution saving throw or advance one stage in the Blighted Scourge infection.

Energy Discharge (Recharge 5–6). The Blighted Sentinel releases a surge of blighted energy in a 20-foot radius around it. Each creature in that area must make a DC 17 Constitution saving throw, taking 36 (8d8) blighted energy damage on a failed save, or half as much on a successful one. Blighted creatures are immune to this effect.

Blighted Guard. When an ally within 10 feet of the Sentinel takes damage, the Sentinel can use its reaction to take half of that damage instead, transferring some of the impact to itself.

The Blighted Sentinel can take 2 legendary actions, choosing from the options below. Only one legendary action can be used at a time, and only at the end of another creature's turn. The Blighted Sentinel regains spent legendary actions at the start of its turn.

• Slam. The Blighted Sentinel makes one Slam attack.
• Blighted Shield (Costs 2 Actions). The Blighted Sentinel generates a temporary barrier of blighted energy, reducing damage taken by 10 for itself or an ally within 10 feet until the start of its next turn.
