Anti-Alien Alarm

This red glass orb contains a complex arcane mechanism. When brought within 60 feet of an aberration, undead, or fey creature, the orb shines brightly and emits a loud alarm sound. Additionally, it creates a protective shield around the holder that gives advantage on all attack rolls, skill checks, & saving throws against said creatures, as well as +2 to AC. However, due to the flashing lights and loud noises, the holder has disadvantage on Stealth checks instead of advantage.

These effects last until this item is no longer near the creature(s) that activated it or the creature(s) die.

"PROTECTIVE SHIELD! PROTECTIVE SHIELD! PROTECTIVE SHIELD! NO DRACULAS! NO MUMMY! NO ALIEN! NO DUENDE!"

Notes: Disadvantage: Stealth, Advantage: Saving Throws, Advantage: Ability Checks, Advantage: Dexterity Attacks, Advantage: Melee Attacks, Advantage: Ranged Attacks, Advantage: Spell Attacks, Advantage: Strength Attacks, Bonus: Armor Class, Buff, Combat, Warding
