Grappling techniques in Fantastic Dungeon Grappling

GMs using Fantastic Dungeon Grappling (FDG for the remainder of this article) in games other than DFRPG or even GURPS Dungeon Fantasy often encounter questions about using various grappling techniques from Basic Set and Martial Arts. Having a technique-happy player create a grappling character for my recently started campaign, I had to answer many such questions myself, so I decided to take a look at all techniques presented in Martial Arts. In this article I will address how those techniques could be treated under FDG as well as how to improve them.

Arm or Wrist Lock, Choke Hold, Finger Lock, Head Lock and Leg Lock are all treated the same way in FDG: grab the desired body part (or just the torso, if the extra -2 to DX for grabbing a specific location is of no concern to you), generate CP, and then convert those CP to damage via Injure the Foe. Any differences originally present between them are below the resolution of FDG.

Grabbing a specific hit location can be improved as a targeted attack with a grab, for example Targeted Attack (Wrestling Grab/Face), while applying injury would require its own targeted attack, e.g. Targeted Attack (Sumo Wrestling Injure the Foe/Arm).

Throws from locks are, as per the example given for a neck lock under I Grapple His Face! on FDG p. 8, simply damaging takedowns. They can be improved as, to give an example, Targeted Attack (Judo Takedown/Neck).

Targeted attacks for grabs use the grappling hit location penalties found at the start of FDG p. 3, which are half of the standard hit location penalties. Those for inflicting damage of any kind use the standard ones. Note that unlike the original grappling techniques, these targeted attacks may only remove half (round in your favor) of the hit location penalty. If closer resemblance of the original techniques is more important to you than systemic consistency, you could allow for these targeted attacks to improve their penalties fully, but this moves FDG away from its concept that grappling should function in the same way striking does.

Hand Catch and Hand-Clap Parry simply become Grabbing Parry as presented on FDG p.3. Improving them would be a separate hard technique for each hit location being grabbed (weapons would count as one).

Armed Grapple is unchanged. It is in fact the Armed Grappling Attack on FDG p. 2 and can be improved as a hard technique. The penalties for grappling a specific hit location can additionally be bought off via targeted attack, for example Targeted Attack (Axe/Mace Grab/Neck).

Bind Weapon is treated as a Weapon/Shield Bind from FDG p. 3 and requires no improvement.

Entangle and Hook are Armed Grapples (above) with a whip or a hooked weapon, respectively, using Long-Distance Grapple from FDG p. 3.

Handcuffing can be treated as grappling the hands, with the extra -2 to penalties using those limbs remaining in place even if you switch your grip to other body parts. The victim should also be flat out unable to take specific actions depending on the position you cuffed them in; while they may be able to wield a weapon at -2 if you cuffed their hands in front of them, they should not be able to do so at all if you cuffed their hands behind their back, for example. Similar GM discretion should be exercised while  handcuffing; you should only be able to cuff a person behind their back if you’re standing in their rear hex. All other special considerations from Martial Arts should be disregarded (yes, the victim can parry your attempt to attach a cuff to an inanimate object – by yanking the chain). To remove the handcuffs, the victim must use the Escape skill. Handcuffing can be improved via Targeted Attack (Judo or Wrestling Handcuffing/Hand).

Judo Throw is treated as an attack on the turn immediately after a successful parry but as a quick contest after a grapple in Martial Arts, even though Basic Set treats it as an attack in both cases. DFRPG follows suit so this move does not require any special treatment under FDG. You may want to decide on how to treat a damaging throw, because it does not exist in DFRPG and it works differently between Martial Arts and FDG. The former assigns an additional -1 penalty to the attack roll and thrust-1 damage without bonus for skill, while under the latter as per Kiss the Wall on p. 8 there is no attack penalty but it does thrust-2 damage with the standard FDG high skill bonus. I would recommend the FDG approach.

Leg Grapple is simply a grapple targeting a leg.

Neck Snap, Wrench Limb and Wrench Spine lose their special status of being ST-based techniques and become simple cases of causing injury to a specific hit location after a grapple. They can be improved with, for example, Targeted Attack (Wrestling Injure the Foe/Neck).

Sacrifice Throw… mechanically speaking, I see very few cases where you’d want to use this technique instead of a normal All-Out Attack judo throw. Maybe you’re counting on your opponent parrying instead of using any other defense, or maybe landing on top of them is of critical importance to you. A deceptive attack judo throw from an All-Out Attack (Determined) is strictly superior otherwise. If you wanted, you could transfer the special effect of this All-Out Attack variant into FDG verbatim and it would work without issue. The downside is the added complexity which you probably don’t want if you’re running FDG in the first place, especially since you can increase your skill (to perform deceptive attacks, for example) via CP expenditure. So unless you’re really into the details, just do a normal judo throw with the desired attack options.

Scissors Hold is just a case of grabbing the opponent by their leg(s) using your own, and can not be improved other than via Targeted Attack (Wrestling Grab/Leg). Use the same posture restrictions as in Martial Arts.

Sweep becomes the iconic example of Sweep the Leg! from FDG p. 8. It can not be improved and does not take any kind of penalty to its attack.

Trip works as described in Martial Arts. It is not really a grappling move, but I’ve included it here for the sake of completeness since it’s a technique for the grappling skills.

Backbreaker is covered under I Grapple His Face! on FDG p. 8.

Binding should be treated similar to Handcuffing. If using cuffs, the only difference is you can also target the victim’s feet. If using a rope, you can also target their arms and legs, but the victim automatically removes the rope from all bound hit locations if they reduce their CP to where they no longer suffer any DX penalty. The exception to this is if you bind all of their limbs; they can then only get rid of the bindings using the Escape skill. Binding can be improved via Targeted Attack (Judo or Knot-Tying Binding/Arm, Hand, Foot or Leg).

Piledriver is just a variant backbreaker targeting the skull instead.

And that covers all of the grappling techniques from Martial Arts. It just shows how Fantastic Dungeon Grappling is both streamlined, flexible and comprehensive.
