You beguile and control a small or smaller beast within range. The spell fails if the beast’s Intelligence is 4 or higher.
While the beast is charmed, you have a telepathic link with it as long as the two of you are on the same plane of existence. You can use this telepathic link to issue commands to the beast while you are conscious (no action required), which it does its best to obey. You can specify a simple and general course of action, such as "Attack that creature," "Run over there," or "Fetch that object." If the beast completes the order and doesn't receive further direction from you, it defends and preserves itself to the best of its ability.
You can use your action to take total and precise control of the target. Until the end of your next turn, the creature takes only the actions you choose, and doesn't do anything that you don't allow it to do. During this time, you can also cause the creature to use a reaction, but this requires you to use your own reaction as well.
At Higher Levels. At 5th level, you can cast the spell on a beast of Medium size or smaller. At 10th level, the spell effects beasts of Large size or smaller. At 15th level, the spell effects beasts of Huge size or smaller, and at 20th level the spell effects all beasts within range.
