The 20 Moon Pearls (5e Equipment)
From D&D Wiki
Wondrous Item, rarity varies (requires attunement)
These moon pearls were created by moon elves, aberrations, air elementals, and other ancient, moon and air species. 20 types of these moon pearls were created, and each of them have special powers. Please note I didn't create all 20 pearls, so please make more if you want (create them above the picture).
Pearl of owls, uncommon
This pearl holds up to 20 charges. You may spend 1 charge to transform you, or someone else into an owl (if unwilling, you must spend 2 charges, and it may make DC 15 Charisma saving throw). When transformed, the creature retains its ability scores, alignment, personality, and magic (in owl form, it can cast spells that don't need material components). Other abilities are replaced by the owl's abilities. Any equipment merges with the new form except armor, which changes shape and size to suit the creature. Gauntlets become metal claws and moon pearls fuse into creatures chest. You may use the moon pearl to deactivate the transformation, or after 6d8 minutes the transformation reverts over the course of 1 minute. You may also summon a swarm of owls with 5 charges (the owls are loyal to you and they disappear after 4d8 minutes). You may spend 3 charges to cause a creature to grow owl wings, and gain a flying speed of 60 ft. You learn owlish, and you may spend 1 charge to grant another creature owlish. This pearl regains 1 charge at dawn.
Pearl of night, very rare
This pearl holds up to 10 charges. You may spend 1 charge to cast darkness as a 3rd level spell. 3 charges turn day to night, and vise versa. You have infinite darkvision, and may spend 3 charges to give another creature infinite darkvision. You may spend 5 charges to cast hunger of hadar. This pearl regains 1d4-1 charges at dawn.
Pearl of wolves, rare
This pearl holds up to 15 charges. While this pearl is on your person, you are a lycanthrope and transform into a werewolf at night. When you transform, roll 1d10, on a 1 you become savage, otherwise you retain your memory. You may also spend 5 charges to transform a creature into a lycanthrope (same type as you), you may spend 3 charges to transform a creature into a wolf and its abilities are all replaced except for ability scores, alignment, and personality. This change lasts until you dispel it as a bonus action. Additionally, you know wolfish, and you may spend 1 charge to grant another creature wolfish, and all wolves are loyal to you. This pearl regains 1d4 charges at dawn.
