You can use an action to speak this staff's command word and throw the staff on the ground within 10 feet of you. The staff becomes a giant constrictor snake under your control and acts on its initiative count. By using a bonus action to speak the command word again, you return the staff to its normal form in a space formerly occupied by the snake.

On your turn, you can mentally command the snake if it is within 60 feet of you and you aren't incapacitated. You decide what action the snake takes and where it moves during its next turn, or you can issue it a general command, such as to attack your enemies or guard a location.

 The Shadowcoil Band is a deep serpent carvings in an obsidian wristband. When activated, its top transforms into a spectral Python that can be commanded to attack with venomous bite. It emits a soft hiss, shimmering with dark essence, with glowing eyes ready to strike.
