Re: Blocking attacks against another character.
 

I'm not sure what you mean. Jumping into an attack meant for someone else is Sacrificial Dodge. Why would you parry or block an attack into yourself? Why would it ever be preferable to just deflecting the blow in the first place?
Like I said earlier PU:2 p. 7 has both perks. Shield Wall Training is on MA page 51 but is identical to the write-up in PU:2.

Re: Blocking attacks against another character.
 

So I got PU 2, and became a little disturbed but I'll bring that up in a new thread.
As pertains to this one, sacrificial parry and shield-wall training has written do not state that others can't try to do them, it also fails to mention what penalties are involved. Penalties others would have and what penalties these remove.

More importantly these are NOT perks, they are techniques (as are many of the combat perks). Anything you can TRAIN in (shield-wall training), or that require specialization are Skills or sub-skills (task or techniques). that's the disturbing part.

Re: Blocking attacks against another character.
 

Why can't you train a perk? Often some particular trained response would be vastly overpriced as a technique. Compare the Basic Set version of Off-Hand Weapons Training with the Martial Arts version.

Re: Blocking attacks against another character.
 

That there's what you call a RULES HOLE!
I don't have MA but did get PU2, and I almost missed it, since it is not listed as combat perk, but a skill perk, and is not called Off-Hand Weapons Training, but called Off-Hand Training. It also refers you to p. B14, not p. B232.
It should apply only to non-combat skills.
And again it is a learned skill something you can pick up during a campaign, as a general rule perks should chosen a character creation.

Re: Blocking attacks against another character.
 

No, it's fully intended that it applies to combat skills. The technique from the Basic Set is deprecated in favor of the perk.
Perks not being acquired after character creation is not any sort of established rule.

Re: Blocking attacks against another character.
 

It costs 4 points to buy off the penalty for a single skill with the technique version. Ambidexterity costs only a single point more, and applies to all skills.
Why?
Why? You can't one day decide to pack a bug-out bag and leave it by the door? Or get a dog? Or hone your awesome mental command of the EM spectrum to let you produce a flashlight effect?

Re: Blocking attacks against another character.
 

G is for generic, there is no errata for this change for basic set, MA is a melee combat sourcebook, (not a World Sourcebook) so the rules from one source to another should by consistent.

[/QUOTE]Perks not being acquired after character creation is not any sort of established rule.[/QUOTE]

Define: any sort of established= if the GM permits p. B32. Where as the GM must approve all changes to characters the book does not bother to state that for skills

Re: Blocking attacks against another character.
 

That's not how it works. The rules of rules precedence, such as they are, don't cut that way.
This is true as best I can tell, but doesn't seem at all significant.

Re: Blocking attacks against another character.
 

Actually it does.

Re: Blocking attacks against another character.
 

I agree there is a point cost problem here.
the write-up says all defense roll, but do not mention attack rolls. See main-gauche p. B208

packed bag, is not an advantage or a skill, rolling to see if you packed a toothbrush is against IQ.
A dog is not an ally or a dependent, beware the cat ladies.
mental command of the EM spectrum (advantage, psi power),produce a flashlight effect skill
