Re: Fast-Draw Parry
While I agree with the principle of your argument, these numbers are incorrect.
Critical success on fast draw = 20/216 = 4320/46656 success on fast draw + success on parry = (192/216) X (108/216) = 20736/46656 total odds of parrying success = (4320/46656) + (20736/46656) = 25056/46656 = 53.7037% 53.7037% is not "about 60%" EDIT: Beaten by VSH |

I think that the odds of regular defence are 13-3=10=50% and the odds of successful Fast-Draw Parry at those skill levels are 9.3% of not having to roll the Parry, 0.5% of not being allowed to and 50% chance in case the Fast-Draw roll falls between 7-16. Doesn't that make for a final chance of, what, 54.4%? Not as much as 60%, true, but still significantly better than 50%. And if the Deceptive Attack was -8 (still within the capability of an equal foe), the automatic defence on a critical success would be even more important. And yes, I'm aware that you can get Enhanced Parry for that price. I'm not saying that this is necessarily unbalanced, I'm saying that allowing people to defend better when their weapon is not Ready than they can do with it Ready fails my reality check and makes combat feel very strange.

I've explained above.

However, I like version with no autoparry better. And "OMFG" effect would be translated into GURPS as Parrying AOA. |

Re: Fast-Draw Parry
Playtesting, as always, is needed. Feel free to say that critical success on Fast-Draw does nothing, gives only +1, etc.

Re: Fast-Draw Parry
I used the numbers from Characters (meaning there is some rounding error) and input things into a spreadsheet. High Fast-Draw does indeed make a noticeable increase in parry chance. Here's how it works out.
Parry 8: FD15 is a +2.2%, FD16+ is +4.3% Parry 9: FD15 is +1.2%, FD16+ is +5.1% Parry 10: FD16+ is +3.7% (FD 15 is, noteably, +0.0%) Parry 11: FD16+ is +2.3% Parry 12: FD16+ is +1.0% Parry 13+: A Fast-Draw Parry is worse than a normal Parry, regardless of FD. Thus, at a final Parry of 12 or lower (I didn't calculate for 7-, but I suspect there is a similar trend), and high Fast Draw, Fast-Draw Parry is slightly better than a normal Parry. As characters with high enough Fast Draw to qualify are likely to have Parry scores higher than 12, this indicates it's slightly more difficult to pull off a successful Deceptive Attack against a character with a sheathed sword than against one with one out and at the ready - provided said character has devoted significant time to perfecting the act of drawing into a parry. With the small increases present, as well as the time the character has spent in perfecting this sort of Parry, I think I'm alright with this - but I tend to err on the side of cinematic frequently. Simply capping the Technique at Parry-1 would be sufficient to insure that it is always worse to draw into a Parry. I'd probably lean toward capping it at Parry-2, but allow the +2 bonus for having a hand on the weapon to increase it up to Parry-1 (this way an expert is still better off with his hand on his weapon). An alternative would be to give an additional penalty that cannot be bought off if the attack is performed against the side opposite where the weapon is sheathed (the Weapon Side Hex and, arguably, the Front Hex immediately adjacent to it for most; all three front hexes if the weapon is sheathed on the back). -2 may be appropriate.

The chances of failed FD check are miniscule and the chances of a critical success are significant.
