Brawn (STR+SIZ)
Brawn is used where physical force (pushing, pulling and lifting)
needs to be implemented; forcing a jammed door, for instance, or
pulling a cart free of a rut in the road.
A character can lift up to his STR x1.5 in SIZ without making a
Brawn roll. As a mass equivalent, 1 point of SIZ equals, roughly,
5 kilograms.
For SIZ and mass above this, the character needs to succeed in a
Brawn roll and if successful he can lift up to three times his STR. If
the roll is a critical success, then up to five times STR can be lifted.
If the Brawn roll is fumbled, the character risks injury: he
must make a successful Resilience roll or sustain 1D3 points
of damage to the Chest Hit Location (armour does not protect
against this damage).
