Nets are weapons. They are often used by water-based races, and are often set with weights, hooks, and/or barbs.

• ENC: 75 cn
• Space required: 10'
• RoF: 1/2
• Range: 1“/2”/3“

WvAC:

• If the attack hits, the target is netted. The target must roll a save vs paralysis;¹⁾ if they fail, they are also trapped.
• Netted creatures lose any DEX bonus to AC (or take a -1 penalty if they have no DEX bonus), are at 50% MV, and cannot charge.
• Trapped creatures are unable able to move, cast spells, or use weapons (except dagger-length or shorter to cut themselves out, as below).
• Both effects last for 1-4 rounds.²⁾
• The victim can take an E action to do one of:
  • Use a bladed weapon of dagger length or shorter to reduce the duration by 1 round.
  • Make an open doors roll, with success reducing the duration by 1 round.
  • Make a BB/LG roll, with success completely freeing the character. This can only be attempted once per netting.

Characters attempting to use an underwater net suffer a -4 to hit unless they've both (1) taken the net as a weapon proficiency, and (2) trained in its use while underwater.³⁾ Above-water nets suffer the regular untrained penalty for lacking the weapon proficiency.

There is no single ruleset for refereeing nets; there are several options provided by various monster entries and modules. Demon Idol uses the WG4 rules and this Dragonsfoot thread as inspiration, and adapts them to suit general-purpose net weapons.
