Aura of Reverence. Wisdom Saving Throw: DC 17, any creature that starts its turn in a 30-foot emanation originating from the monolith. Failure: The target becomes magically charmed. While charmed that way, the target defends the monolith at all costs, even its own life, and tries to stay close to it. Whenever the creature ends its turn further away than 30 feet from the monolith, it can repeat the saving throw, ending the effect on a success. Success or Effect Ends: The target is immune to the monolith's Aura of Reverence for the next 24 hours.
Heavy. The monolith can't be moved or toppled unless an effect is able to move 20,000 pounds or more.
Immutable Form. The monolith can't shape-shift.
Impervious. The monolith has a damage threshold of 10.
Magic Resistance. The monolith has advantage on saving throws against spells and other magical effects.

QUICK REFERENCE
USING MONSTER VARIANTS
Monster variants allow the GM to adjust encounters to better match the party’s strength, narrative needs, or world-building logic. A weaker variant may represent a juvenile, wounded, or lesser specimen, while a stronger variant can serve as a leader, champion, ancient creature, or apex predator.
Variants can be used to fine-tune difficulty without changing the core identity of the monster, making them ideal for scaling encounters, reinforcing hierarchy within a faction, or creating memorable boss-style enemies. You can even use the same stat block but different variants in the same encounter if you want.
Design Note. Each monster is primarily balanced around its normal version. Weaker and stronger variants are derived adjustments and may not always preserve every tactical nuance or “feel” of the original creature. GMs are encouraged to review variants carefully and adjust abilities or tactics as needed to best suit their table.
