Casual strength for weaklings

[Truls]

How do you handle casual strength for negative strength scores (or zero strenght). If someone has STR -10 what would his casual strength be? Just halving his strength score doesn't work, as that would make his casual strength higher than his normal strength.

Determine what the character can lift with his STR. Take half of that, then determine the amount of negative STR needed to lift that, and use that for his Casual STR. For example, -10 STR can lift 6.4 kg. Half of that is 3.2 kg. A -15 STR can lift 3.2 kg, so that’s what the characters’ Casual STR is.
