Innate Spellcasting. The Guardian's innate spellcasting ability is Charisma (spell save DC 13). The Guardian can innately cast the following spells, requiring no material components:
At will: darkness, invisibility
1/day each: charm person, cone of cold, gaseous form, sleep
Magic Weapons. The Guardian's weapon attacks are magical.
Regeneration. The Guardian regains 10 hit points at the start of its turn if it has at least 1 hit point.
Multiattack. The Guardian makes two attacks, either with its claws or its greatsword.
Claw (Guardian Form Only). Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 8 (1d8 + 4) slashing damage.
Greatsword. Melee Weapon Attack: +7 to hit, reach 10 ft., one target. Hit: 18 (4d6 + 4) slashing damage, or 11 (2d6 + 4) slashing damage in Small or Medium form.
Change Shape. The Guardian magically polymorphs into a Small or Medium humanoid, into a Large giant, or back into its true form. Other than its size, its statistics are the same in each form. The only equipment that is transformed is its glaive, which shrinks so that it can be wielded in humanoid form. If the Guardian dies, it reverts to its true form, and its greatsword reverts to its normal size.
Slay or Slumber. When an enemy within the Guardian's lair fails to attack the Guardian, he may cast a limited sleep spell targeting only that enemy rolling only 3d8.
Steal the Heal. When an enemy with 60 feet of the Guardian receives healing, the Guardian gains half the amount healed as temporary hit points.
Ogre Mage Guardians watch over ancient sites of prophecy and keep mystical items safe from the unworthy. If defeated, many ogre mage Guardians will relentlessly hunt down their enemies to retrieve anything stolen from the lair they guard.
An example of an Ogre Mage Guardian is the remnant of the DéDannan that lives in an ancient ruin on the peak of The Thunderhorn. This DéDannan Ogre Mage Guardian was a disciple of Táin McLir thousands of years ago. His solemn duty was to guard an ancient greatsword for a prophesied champion: “The one who will wield ignorance as a weapon.” The weapon is The Bloodsword of The Ignorant a DéDannan Bloodsword carved from the living stone of Thunderhorn.
Lair and Lair Actions
Elusive. While in his lair the guardian may cast darkness or invisibility as a bonus action and maintain concentration on both.
Grasshopper Leap. Once per round the Guardian can fly to any square in his lair without provoking opportunity attacks.
Unrelenting. A Guardian gains an additional reaction for every enemy in his lair.
Dramatic Exit. When the Guardian is reduced to 0 hit points while in his lair, he is instead reduced to 1 hit point and he immediately smiles. He then uses either a reaction, a lair action or a bonus action. Once this action is complete he is instantly affected by a gaseous form spell and then an invisibility spell. The Guardian cannot regain physical form until the next sunrise. This effect does not function if the killing blow is made with a blessed stone weapon that strikes the neck (AC20).
