Magic Resistance. The cadaver collector has advantage on saving throws against spells and other magical effects.

Summon Specters (Recharges after a Short or Long Rest). As a bonus action, the cadaver collector calls up the enslaved spirits of those it has slain; 3d4 hardened specters (without Sunlight Sensitivity) arise in unoccupied spaces within 15 feet of the cadaver collector. The specters act right after the cadaver collector on the same initiative count and fight until they’re destroyed. They disappear when the cadaver collector is destroyed.

Multiattack. The cadaver collector makes two slam attacks.

Pierce. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 10 (1d10 + 5) piercing damage.

Disorienting Blast (Recharge 5-6). The cadaver collector releases a blast of deafening sound and blinding light in a 40-foot sphere. Each creature in that area must make a successful DC 18 Constitution saving throw or be Deafened and Blinded for 3 rounds. A creature repeats the saving throw at the end of each of its turns, ending the effect on itself with a success.
