Judo is a striking skill

[Plane]

MrFix re your initial list, one omission I just noticed is Pummeling, which MA101 lets you roll against DX-1 to hit with weapons.

This explicitly says "reach is always C" though (not sure if being SM+10 would override that or not) which would make the omission of "Judo-1" from that list even more innocuous, were it actually intended.

There is definitely a 'desire to help the defender' manifest in the errata for basic set. It's basically a "let's pretend they're not in close combat in a way which benefits the defender and not the attacker because they only just entered it this second" approach.

Without that errata, reach 1 weapons could not parry attacks if the attacker stepped into close combat. Now they can, as long as that step happened in the same turn as the attack.

The errata was no surprise, as there was already something of this idea with Runaround Attack rules, where you count as attacking from the side instead of the back, so long as you didn't begin your turn in the back.

It's the same principle: favor the defender as if circumstances were as they were at the start of the turn before the attacker did anything.

If he wasnt in close combat, he wouldn't get the penalty.

Hence, if he gets the close combat penalty - he's in close combat.

Based on the errata, when an attacker steps into close combat, the defender doesn't count as being in close combat in terms of parrying when defending on that turn.

I think this would probably still apply even with Martial Arts giving us rules which allow long weapons to parry in close combat: those would only apply on subsequent turns after the attacker stepped in.

Allowing a defender to avoid a -2 penalty to parry is kind of similar to giving the attacker a -4 to skill if he wouldn't spent that skill on a deceptive attack.

So I'm thinking penalize the attacker in another way: make the judoka wait until he's actually started his turn in close combat before allowing this "punch with judo" idea.

In any situation that you can make a C-range Knife attack or Boxing punch, you can make Judo Punch.

C-range knife attacks can be made against the limb of an unarmed attacker on a successful parry, even if that attacker wasn't in close combat.

It would be a stronger limit for punches if we made the AOA (Long) effect more accessible. Aside from burning valuable FP on Extra Effort. Technical grappling had Committed Attack (Long) which imposed a damage (well, control point, but damage is easily subbed) penalty (similar to Defensive Attack) instead of completely crippling defence.

I'd just make it a -4 to skill technique to do a +1 reach lunge.

I don't remember that, do you recall where you saw it? I assume you mean a "straight up DX minus 2 kick" in the 2nd case, unless you're talking about kicking at DX-0 while lying face-up on one's back.

Was this maybe part of some idea of untrained people getting to use brawling at default? Non-defaults skills getting defaults is an idea promoted with "Wizardly Dabbler" so I'm fine with it.

Did you maybe mean 'technique roll' ? MA75 has "Kicking" which mentions the Brawl/Karate defaults but not the DX one. Punching isn't mentioned, I think because it's a primary-use technique which can't be bought up separately from the underlying skill (much like grappling)

Fun fact: this was actually a broader issue in 3e when Wrestling was added as the 2nd grappling skill and Sumo was added as the 3rd...

Page 243 of 3e's Basic Set:

You can use your Wrestling skill to replace DX in Close Combat, just as for Judo.

Which I figure refers back to page 51:

You may also use your Judo skill, instead of your DX, in any DX roll made in Close Combat except to draw a weapon or drop a shield.

Page 35 of 3e's Martial Arts:

You can substitute Sumo Wrestling for DX in these contests, and for any other use of DX in unarmed Close Combat.

That doesn't call out Judo specifically like Wrestling did in the 3e basic set, but I think "unarmed" would clearly also rule out not only weapon-drawing and shield-dropping, but Pummeling too. Not punches though =/

Looks like Wrestling and Sumo Wrestling got nerfed in 4e since B228's and B223's description of them did not retain that note from 3e's B243/MA35...

Or maybe these Wrestling/Sum notes removed to avoid this confusion regarding punching, and they intended but forgot to remove it for Judo?
