Cadmus (5e Equipment)
From D&D Wiki
Weapon (Dagger), artifact (Requires attunement from "The One Blessed by The Dragon" (make of this what you want in your campaign))
This dagger's blade is the tooth of a dragon, an extremely old and powerful dragon. It has an ornate hilt that looks like very sharp human canine teeth. This sacred artifact was granted to the mortals by Bahamut himself. The Cadmus, which can only be wielded by the one with the "Blessing of the Dragon," has the power of bringing forth to life the children of dragons and the servants of Bahamut.
Bringer of Life The Cadmus has 4 charges. With an action the wielder can burrow the dagger in the ground and say the prayer: "With this blessing I bring forth your children!" After doing that the blade of the dagger will come off (the blade comes back in 1 minute), and where the dagger was burrowed a Young Gold Dragon grows (as soon as it grows you must use your bonus action to give it 1 command), which it will follow to the best of its abilities. The dragon will stay with you until it finishes its command, or for 20 minutes (if it can't complete its order).
Bringer of Unlife The Cadmus has 6 other charges. With an action the wielder can burrow the dagger in the ground and say the prayer: "With this blessing I bring forth your followers!" After doing this, or more of the canine teeth come off (they grow back in 10 minutes each), and where the teeth were burrowed 1-6 "Followers of Bahamut" appear (they have the same stats as a Wraith, but look like priests wearing dragon masks). They vary in appearance and races, but their statuses are the same. They work the same way as the young dragons, but they stay for 1 hour. And if they finish their command, another one may be given, until the time ends.
Honor of Bahamut The dagger inflicts an additional 4d6 damage against chromatic dragons.
