I've addressed these before but I figured it wouldn't hurt to do so again:
FiveCore and status effects:
A "Status" in FiveCore is an involuntary state you are in, because of an incoming attack.
The possible status effects from least to most bad are;
Pinned (1 on Shock dice, while in cover).
Hunkered Down (1 on Shock dice, out of cover)
Bailed (6 on Shock dice)
Down (1 on Kill dice).
Specific systems use alternate terms for these but the effects are the same.
A figure or stand is never, ever, under any circumstances, subject to multiple status effects. If a status effect would change, the previous status is discarded immediately and completely.
For example, if a Bailed figure goes Down, he is now Down. He does not have to recover from being Bailed, abilities that help him recover from Bailed status do not help him and once he recovers from being Down, he is not Bailed.
In case of two status effects applying, apply the most severe (from the list above) and ignore all other effects.
If I shoot at a Bailed figure and get a Down result, he is now Down. If I shoot at a Downed figure and get a Bail result, nothing happens (because the more severe effect is Down).
A figure in cover must declare if they are firing or hiding. If they fire, they can be fired upon with NO reduction in firing dice.
If a line of fire crosses a terrain feature that neither firer, nor target, touches, the Kill dice are dropped and the attack is Shock dice only.
This ONLY applies if the fire crosses the terrain feature and neither figure is touching that feature.
If you fire into a wood where a figure is placed, you do NOT drop Shock dice.
When dice are rerolled, the original score is always discarded and the new roll is applied. This applies in all NWG games, unless explicitly stated otherwise.
If a roll allows you to roll twice and pick the best result, it means just that: Roll two times and choose either result.
In theory, either result could be rerolled, which would take place before you select which of the final results applies. I don't think there's any situation that causes that to happen, but just in case, here you are.
Abilities that allow a reroll on a specific dice result (such as always rerolling a 1 on assault dice) apply to all future rolls, unless stated otherwise.
For example, if you always reroll 1's on assault dice, keep rolling until you get a score that is not a 1.
Opposed rolls and rerolls:
If an opposed dice roll (like a Brawl/assault) allows a reroll, unless explicitly stated otherwise, both players must roll, before electing to reroll.
If both sides have a reroll, write down if you are rerolling or not. Optionally, cancel out the rerolls but its more interesting the other way.
