  • Unchangeable Form. The sentinel of the ancestors is immune to any spell or effect that would change its form.
  • Magic Resistance. Some sentinels of the ancestors are equipped with a stone shield that gives it advantage on saving throws against spells and magical effects.
  • Magical Attacks. The sentinel of the ancestors’ attacks are considered magical for determining what it can damage.
  • Shudder Arm. When a sentinel of the ancestors is hit in melee, the attacker must make a DC 14 Strength saving throw. If the character fails, the strength of the stone has quivered up the arm to the body of the attacker (1d4 points of damage) and you must check to see if their weapon shatters (see below).
  • Shatter Weapon. If an attacker was affected by Shudder Arm and hit the sentinel of the ancestors with a non-magical weapon, or non-adamantine weapon, they must make another DC 14 Strength saving throw or their weapon shatters against the stone.


  • Multiattack. The sentinel of the ancestors (Advanced) makes two attacks with its Stone Axe.
  • Stone Axe. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 8 (1d8+3) bludgeoning damage.
  • Hurl Rock. Ranged Weapon Attack: +4 to hit, range 40 ft., one target. Hit: 7 (1d6+3) bludgeoning damage.


The sentinel of the ancestors is a variant construct akin to an archaian sentinel or caryatid column. They appear as stone statues, pillars, or columns in the form of dwarven warriors. Sentinels will often guard important locations like a vault or crypt of an ancestor.

They remain inanimate until someone disturbs the place they have been assigned to protect. They are made of a granite strengthened and reinforced with dwarven stonecraft and clerical magic.

The greater sentinel of the ancestors is similar to the regular sentinel insofar as they appear as statues or columns of dwarven warriors. However, the greater Archaian sentinel is constructed with stronger enchantments and has greater hit points.
