Lasso:

This weapon does no damage in game terms. A successful
hit, however, effectively creates the same situation as does a successful
harpoon hit, only the lasso must be broken or severed to detach
it if the wielder is exerting force to keep it taut.

There is a 75%
chance that the victim will be dismounted, andlor a 25% chance that
the victim will be pulled off its feet if the target is bipedal and of a
height and mass not greater than + 50% of the lasso wielder. Note
that several creatures can combine to make this more probable, i.e.
rider and mount, several individuals seizing the other end of the lasso
line, etc. A lasso is severed by 2 points of cutting damage. Strength
can snap a lasso, with a chance equal to that of bending bars, but only
one such attempt is allowed in any given instance.
