Sacrifice Throw
Hard
Default: Judo.
Prerequisite: Judo; cannot exceed prerequisite skill level.

This technique involves grappling your opponent, falling with him, and using your entire weight to throw him. It’s risky, but difficult to resist. You may only attempt it if a regular Judo Throw (p. 75) would be possible; that is, on your turn immediately following a successful Judo parry or grapple. Sacrifice Throw is a special option for All-Out Attack (p. B365). Use these rules instead of the standard ones for All-Out Attack.
Before you attempt the throw, you must declare whether you intend to land face-up, face-down, or kneeling, as well as where you plan to end up. One of your landing hexes – the only one, in the case of kneeling – must be your hex, your foe’s hex, or a hex adjacent to one of these. You must also state whether you want your victim to end up face-up or face-down, and where, subject to identical restrictions. You can end up in the same place; that is, you can land atop him or pull him down on top of you.
After stating your goal, roll against Sacrifice Throw to hit. Succeed or fail, you immediately end up in your declared posture and location, defenseless due to your All-Out Attack! Your opponent has -1 to dodge or block. He’s at -3 to parry if you fell or at -2 if you only dropped to your knees. If he fails to defend, you throw him exactly as you planned. If you were grappling him, you may let go as a free action, but you don’t have to – it’s common to hang on and follow a Sacrifice Throw with a pin or choke.
This throw is dangerous in combat but common and useful in point-based matches.
