Nets are martial, ranged weapons made out of overlapping strips of leather of fabric with weights. They do not do any damage, and are made for trapping creatures, and can be used within 5 feet of an enemy without any restrictions and have the Special and Thrown properties.

Properties

Special: Capture
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.

Thrown (10/20)
If a weapon has the thrown property, you can throw the weapon to make a ranged attack. If the weapon is a melee weapon, you use the same ability modifier for that attack roll and damage roll that you would use for a melee attack with the weapon.

Superior Strike

Trip.
You perform a wide, sweeping attack that strikes at the footing of enemies around you. Each creature standing within 10 feet of you must succeed on a Dexterity saving throw or take bludgeoning damage equalling a number of d4s equal to your proficiency bonus and fall prone.
