Bind Weapon
Hard
Default: prerequisite skill-3.
Prerequisite: Jitte/Sai or any fencing weapon skill; cannot exceed prerequisite skill.

Fencers with swords that have crosspiece hilts can lock blades or hilts in a so-called bind. With a pronged weapon such as the jitte (p. 217), it’s possible to bind any weapon. This technique covers all such tactics.
To bind, you must first successfully parry your opponent’s fencing blade with your own such sword – or use a Jitte/Sai weapon to parry any weapon. On your first turn after the parry, roll against Bind Weapon to try to bind the weapon you parried; this is an attack. If you’re using a fencing weapon, your adversary must be within a yard and you must step into close combat. With a Jitte/Sai weapon, the target weapon must merely be in reach (see p. B400).
Your foe’s only legal defenses are a dodge or a parry with the targeted weapon. He may retreat for the usual bonus. If his defense fails, you bind weapons – and if he tried to retreat, he can’t step back.
You can use Bind Weapon offensively rather than after a parry. Step into range (see above) and roll against Bind Weapon to hit. The only difference is that your foe may try any defense, not just a dodge or a parry with the target weapon.
While a bind is in effect, neither fighter can use the weapons involved to attack or defend. All other actions taken by defender and attacker alike are at -2 DX.
Your foe may attempt to free his weapon on his turn. This counts as an attempt to break free (p. B371), and requires a full turn and a Quick Contest of his weapon skill against your Bind Weapon technique. If he uses finesse to disengage, make DX-based rolls. If he uses brute force, the rolls are ST-based. If he wins, the bind ends – and if he used ST, you must make a skill or Retain Weapon roll or drop the weapon you used to bind!
Either of you can escape by dropping the weapon in the bind. This is a free action at any time. You can end the bind without losing your weapon. This, too, is a free action – but only on your turn.
This tactic is common for two-weapon fencers – especially those with a main-gauche. The objective is to bind the enemy’s blade and attack with a secondary weapon. Jitte/Sai fighters use paired weapons to similar effect.
