Originally in Technical Grappling, Grip ST – how many dice you get to roll when you grab someone – was figured differently. During revision, it was changed, and during playtest, it was altered, folder, spindled, and mutilated.
Ultimately, I decided to go with a precise way to combine limbs when grappling. Figure out the contribution in pounds of force (represented by Basic Lift) of each limb or pair of limbs depending on bioloty, add ’em up as Basic Lift, and figure out the ST required to produce that level of Basic Lift.
The advantage here is that it didn’t produce insane numbers, and it also gave a great way to figure out the grappling power applied when you’re dogpiled by seven kobolds or something. Take their Trained ST, square each one, add that value up, and take the square root.
But ew. Hot mess at the table, with or without the handy chart.
+Peter V. Dell’Orto and I have looked at some of this, and found a nice solution for certain parts. But ArchonShiva over at Further Up the Spire has come up with a fast way to work it. It might not be accurate in all cases, but it’s way more tractable at the table.
So go check out Manageable Grip ST in Technical Grappling and see what he’s all about.
