The guardian stela is immune to any spell or effect that would alter its form, and it treats critical hits against it as normal hits. \n'b'  Sacred Link . A guardian stela can perform a ritual taking 1 hour to attune itself to another creature. Once it has done so, the linked creature becomes more watchful, gaining a +1 bonus on  Wisdom  ( Perception ) checks and  initiative  rolls. It receives warnings from the guardian stela\xe2\x80\x99s  alarm  spells and can pass freely through an  arcane lock  created by the guardian stela. If the linked creature takes damage while within 30 feet of the guardian stela, as a  reaction  can either cast hellish rebuke on the creature that damaged its linked creature or else the guardian stela can take half of that damage instead of the linked creature. A creature that fails its saving throw against the guardian stela\xe2\x80\x99s hex deals an extra 1d6 necrotic damage whenever the linked creature hits it with an  attack . A creature cannot be linked to more than one guardian stela. \n'b'  Watchful Guardian . The guardian stela can see  invisible  creatures and adds double its proficiency bonus on  Wisdom  ( Perception ) checks and on  Dexterity  saving throws.

This  arcane lock  remains in place until dispelled or until the guardian stela moves away from it for more than 1 hour. \n'b'  Innate Spellcasting .

Guardian stelae are imbued with mystic power to serve as sacred guardians for those within the temples, monuments, or palaces they protect. They may be carved in the likeness of the one they protect or created in their honor to protect others.'
