When you push your roll in combat, each 1 reduces the reliability of the weapon by one, or if you are fighting unarmed the PC.
Q. Does this damage to reliability carry over to the PC if reliability goes below zero in one of the players turns. For example, a beer bottle has a reliability of 1, I roll two 1s when pushing the roll, the reliability of the bottle is now -1 (can’t see anything in this para that states the reliability cannot go below zero) does any damage below zero carry over to the PC. This would make sense from a narrative standpoint, bottle breaks cuts PCs hand.
