Attacks with this weapon cannot be parried or block. Instead of dealing damage, a successful attack with this weapon forces the opponent to make a Strength or Agility test. If they fail, they gain the Entangled condition. They can spend 1 AP as a Secondary Action to repeat the test, freeing themselves and removing the condition on a success.
If this effect was applied by a melee attack, then should the target character leave the melee range of the Entangling weapon, the character wielding the weapon must choose to either let go of their weapon (maintaining the effect on the target) or keep their weapon (removing the effect from the target).
