Condition
The state an item (a weapon or a piece of armor) is currently in, displayed as a numerical value. 100 means that the item is brand new, 1 means that it is almost completely broken. The repair skill is used to maintain the condition of such an item. If the weapon's condition falls to 0, it will become beyond repair.
If a player or NPC dies while standing, the condition of that person's armor will be decreased by 75. In most random encounters, this will mean that the armor will become beyond repair.
Editor's note: Deterioration article needs to be updated and then merged with this. "Condition" is the new word for Deterioration, but most of the mechanics behind them are the same, except now, a broken item cannot be repaired, and high Condition is good, while low Deterioration is good. Also note that vehicles still use Deterioration as opposed to everything else.
