A character can resist being swept away by a current, if his/her dice roll result against ST + Swimming (including Swimming strength/Resisting currents specialisms) is greater than or equal to a difficulty value, based on the current strength.
Typical difficulties vary as follows:
|Gentle current (e.g. slow river)||2 or lower|
|Quite strong current (e.g. normal river, normal sea)||3-5|
|Strong current (e.g. minor ocean current, tidal flow in estuary)||6-10|
|Very strong current (e.g. fast-flowing river, major ocean current, rip tides)||11-16|
|Irresistible current (e.g. mountain torrent)||17 or more|
A character who fails the dice roll will be carried along by the current.
