[I Smell a Rat Minor Spoiler]Extra Attacks
 

Minor Spoiler for "I Smell a Rat".

I was prepping for the Peshkali encounter in " I Smell a Rat" and had a question about Extra Arms and Extra Attack. I've searched the Forums and Google but did not see this explicitly discussed.

If an individual has both Extra Arms and Extra Attacks like the Peshkali does (6 of each) as well as weapons to go along with them, how many if any of the attacks are treated as Off-Hand in reference to the -4 Penalty? Do multi-Arm creatures still only have 1 Main Hand so ALL other attacks are Penalized? Or does the high point cost of Extra Attack (25 points EACH) allow them to attack un-penalized? I tend to think this would be the case but my Google-fu failed me this time.

[Edit]

OK, well I found the clear rules in the GURPS Basic Set (B54). It still seems odd that a multi-Armed creature only has 1 Main Hand.

None. Monster descriptions are meant to be quick to use. Since the description of the peshkali says "Weapons (18): Six clubs (3d+3 crushing), scimitars (3d+3 cutting or 2d impaling), or spears (2d+1 impaling). Reach 1.", you can assume that all six have skill 18, do the listed damage, and have reach 1. How the monster manages to accomplish that isn't important; as the "Attacks" paragraph on p. 15 of Monsters notes, "The given skill, damage, reach, etc. already factor in the effects of the being's other stats."

When ordinary PCs buy Extra Attack from a template, that's another story. See the "Limbs" paragraph on p. 49 of Adventurers.

That is very helpful. I did end up finding the related rules elsewhere that explain how you get there, knowing that the Monster Stat Block already counts all of that really helps.

Thanks.

To be blunt: Monsters in the Dungeon Fantasy Roleplaying Game cheat. They have all kinds of implied and hidden benefits to keep their stat blocks from getting too terribly long. The chapter intro on p. 9 of Monsters says it best . . .
