The phaerimm discerns the location of all magical auras within sight and knows which creatures within 60 feet are spellcasters.
The phaerimm can concentrate on two different spells at the same time. If concentration is broken, then both spells fade immediately.
The phaerimm is immune to any spell or effect that would alter its form.
The phaerimm has advantage on saving throws against spells and other magical effects.
The phaerimm is a 15th-level spellcaster. It's innate spellcasting ability is Charisma (spell save DC 19, +11 to hit with spell attacks). It can innately cast the following spells, requiring no material components: • Cantrips (at will): mage hand, minor illusion, poison spray, ray of frost • 1st level (4 slots): dissonant whispers, magic missile, shield • 2nd level (3 slots): crown of madness, detect thoughts, phantasmal force • 3rd level (3 slots): fireball, fear, hypnotic pattern • 4th level (3 slots): confusion, greater invisibility, phantasmal killer • 5th level (2 slots): dominate person, hold monster, telekinesis • 6th level (1 slot): chain lightning, mass suggestion • 7th level (1 slot): prismatic spray, reverse gravity • 8th level (1 slot): dominate monster
The phaerimm makes four attacks with its claws and a bite or stinger attack. Alternatively, it attacks with two claws and casts one spell.
Melee Weapon Attack: +10 to hit, reach 10 ft., one target. Hit: 12 (2d6 + 5) piercing damage.
Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 14 (2d8 + 5) piercing damage.
Melee Weapon Attack: +10 to hit, reach 10 ft., one target. Hit: 12 (2d6 + 5) piercing damage. If the target fails a DC 18 Constitution saving throw, they will be paralyzed for 1 minute. The phaerimm's poison forces the paralyzed target to float five feet above the ground. The target may repeat the saving throw at the end of each of it's turns.
The phaerimm uses an action to do a stinger attack against a paralyzed target. If the stinger hits, an egg is implanted in the target. This egg can only be removed by spells that cure disease, such as lesser restoration. If the egg is not removed within 90 days, the larva emerges, and the host is killed. A phaerimm has a single egg so may only use this ability once.
