[Technical Grappling] Faster Grip ST calculation for Extra Arms (and efficiency)
Greetings, all!
Looking at my crazy idea of seeing how TG handles a cephalopod, I realised what a slow, slow process the calculation of Grip ST is. (Figure number of limbs used in a given grapple [including which ones of them can be legally paired!], add, square, multiply, take a square root.) That seems tedious for something in the middle of a combat. Instead, there's a shorthand way to do it without checking through the BL table. Assuming we start with a two-armed creature, and that 'Base Grip ST' is the Grip ST of a two-armed grapple, adding more arms has the following effects:
How did I arrive at those numbers?
Spoiler:
Conclusions: Based on TG rules, Extra Arms have diminishing returns for purposes of Grip ST / Control Points. The +2 per extra arm to all rolls to Grapple, Break Free, and to prevent an opponent's attempt to Break Free, OTOH, is still a very, very cool thing. The flat +2 ST to Choking being replaced with a percentile-and-diminishing bonus to Grip ST means that the whether Extra Arms are a point-efficient investment for boosting Choking will depend enormously on the number of arms and the base ST of the character. Somewhat subtly, having Stretching and increasing your limb SM by 1 seems like the cheapest way of attaining +1 DX and +15% Trained ST from p. 9, as opposed to buying the Long enhancement to do the same (since you don't really need +swing for grappling except in rare cases). Comments? Additions? Thanks in advance! |
