Each successive dodge roll during a turn, unless it is a dodge against the same object or character, will get a -1 bonus.
If you are Stunned, Dazed, or otherwise receive a temporary penalty to overall or individual rolls, this penalty lasts until your next action is resolved, and not through the whole turn.
If you receive a long-term effect that has the potential to alter itself, you get an Effect Resistance roll immediately after your action is resolved to determine the spread and consequences of the effect.
If you are Unconscious, whatever penalty you receive will not reduce your roll score below 2, unless stated otherwise.
If you receive a mortal wound but are not killed outright, you need to pass a roll to dodge Death at the end of every turn. Only bad rolls here will provide penalties to survival rolls.
You can spend your turn to help another player achieve his goal. If your roll is higher, it is taken as the success roll for the action.
You can also spend your turn to botch another player's action. If your roll is higher, its opposite is taken as the success roll for the action.
In both cases, individual player rolls determine what happens to the players in the course of the action.
