Shen Feng Wa used this net to defeat Lady Rocky, who was much more powerful than he was. 

Whenever a creature is restrained by this net until the start of your next turn you can use your reaction to speak the command word. Doing so summons nine adult bronze dragons to unoccupied spaces within 100 feet of the user.

The dragons are friendly and loyal to the one attuned to this net. If they are not given any instructions, they act in any way they deem necessary to protect themselves and you. They remain for 1 hour, after which they fly away and the net becomes nonmagical before harmlessly disappearing in crackling flames. 

Proficiency with a net allows you to add your proficiency bonus to the attack roll for any attack you make with it.

A Large or smaller creature hit by a net is restrained until it is freed. A net has no effect on creatures that are formless, or creatures that are Huge or larger. A creature can use its action to make a DC 10 Strength check, freeing itself or another creature within its reach on a success. Dealing 5 slashing damage to the net (AC 10) also frees the creature without harming it, ending the effect and destroying the net.

When you use an action, bonus action, or reaction to attack with a net, you can make only one attack regardless of the number of attacks you can normally make.
