Mytholabe 2014
CR 9 construct
Large construct, unaligned
The mytholabe is immune to any spell or effect that would alter its form.
The mytholabe can innately cast plane shift on itself only, requiring no material components. Its innate spellcasting ability is Wisdom.
The mytholabe has advantage on saving throws against spells and other magical effects.
The mytholabe's weapon attacks are magical.
Whenever the mytholabe is hit by a magical weapon attack, it recharges its Purifying Resonance ability.
If the mytholabe is inhabited by a sentient weapon, its mental statistics and alignment change to match that of the weapon's.
When the mytholabe suffers a critical hit from a nonmagical weapon, the attacker quadruples the dice rolled instead of doubling them.
When the mytholabe is hit with a nonmagical melee weapon attack, each creature within 15 feet of it must succeed on a DC 16 Constitution saving throw or be deafened for 1 minute.
Actions
The mytholabe makes three heroic jab attacks. When its Purifying Resonance is available, it can use the resonance in place of one heroic jab attack.
Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 9 (1d8 + 5) piercing damage plus 7 (2d6) radiant damage.
The mytholabe thrums with a harmonic resonance that brings order to those within 30 feet. Each creature in that area must succeed on a DC 16 Constitution saving throw or have all conditions and magical effects on it ended immediately and any concentration it's maintaining broken.
