Topic: Two Weapon Combo Fumble Ranges

[arakish]

I have been searching for this, but have had no luck.

What is the Fumble Range for a Two Weapon Combo?

The method I have been using is:
Fumble Range for TWC is calculated by adding +2 to the Fumble Range of the weapon with the largest Fumble Range.

Sword/Dagger TWC Example:
Sword Fumble Range = UM01-04.
Dagger Fumble Range = UM01-02.
Thus, TWC Fumble Range = UM01-06.

What are y'all's ideas?

Why would it be different than the fumble range for the weapon you are attacking with? Especially if you use two weapons with different fumble ranges, why would one be made worse by the other?

My Answer:
I don't know.  I found it in an old text file (date/time stamp = 19870610-1639; filename = twcfr.txt (back in the 8.3 convention)) from my old campaign world of Udava.  Wondered about it, searched through the books I have and the forum boards, finding nothing about the Fumble Range for TWC.  Thus, I posted the above to see what responses I would get.  I am guessing it was from an old discussion with a player group, and I wrote it down using Windows Notepad.

Could it have been from one of the Rolemaster Companions (RM2)? I think the companions offered several TWC options, and seem to remember one option was to add together the fumble ranges of the two weapons. That was I think in RMC IV. But I think that you added the fumble ranges only to find out how many ranks you needed to become fully proficient in the combo.

id add both fumble ranges together. Taking the highest number range for each weapon.
eg. 1-2 plus 1-4 = 1-6

[Malim]

Since you make a roll for each weapon. You can fumble with each weapon!

[jdale]

Suppose the fumble number for each weapon is 3. If you were fighting with one weapon, the odds of at least one fumble in 10 rounds are 26.25%. Fighting with two weapons, the odds of at least one fumble rise to 45.6%, just because you have twice as many opportunities to fumble. If you also add the fumble ranges together, so each weapon fumbles on 1-6, the odds of at least one fumble rise to 71%.

I don't think TWC needs a increased Fumble, never have. You are already, as Jdale points out, More likely to acheive a fumble over the same period of time.

Thanks jdale.

As posted, I guess the text file came from a discussion from when dinosaurs walked about.

Thanks for pointing out the probabilities.

I went through my RM2 books last night to see what I could dig up on Two Weapon Combo in general and I didn't find anything regarding fumble ranges, only negatives for using TWC, development costs, parrying limitations, proper use, etc.  In the sessions we ran, I *believe* we used the normal fumble range for each weapon as you are making a single attack with each weapon.  TWC eliminates the -20 for the off-hand attack, but imparts -25 if you choose to fight with only 1 weapon from the TWC pair (unless you've also developed use of that weapon as a non-TWC skill).

I looked in RMC-II, AL&CL, and Arms Companion (all RM2 books).  Surprisingly, there was nothing in Arms Companion.

another couple house rules option, to help limit sniping and ambush:

#1 bonus is reduced by level of target

#2 limit use of ambush to required anatomy or biology skill. you only get to use a % of ranks bonus to adjust = to % of anatomy/biology skill for that race.
