Netgun: Ranged Weapon Attack: +3 to hit, range 20/60 ft. Hit: 1d8 slashing damage. 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 17 Strength check, freeing itself or another creature within its reach on a success. Dealing 15 slashing damage to the net (AC 12) also frees the creature without harming it, ending the effect and destroying the net. A creature that starts its turn restrained by the net takes 4 (1d8) slashing damage.
