Horn of Nature's Call (5e Equipment)
From D&D Wiki
Wondrous item, rare (requires attuenement by druids, rangers and oath of ancients paladins)
As an action, you can blow this horn. After blowing this horn, you summon 1d4 beasts of challenge rating 2 or lower of your choice.
The creatures are friendly to you and your companions, and it acts on your turn. You can use a bonus action to command how the creature moves and what action it takes on its next turn, or to give it general orders, such as to attack your enemies. In the absence of such orders, the creature acts in a fashion appropriate to its nature.
Once you blow this horn, you can't do it again until the next dawn.
