Use this page when a guide or trade message contains an unfamiliar abbreviation. A player-written shorthand can be ambiguous, so inspect the item or system before committing to a trade.

Similar words, different rules

An item option's chance is not a monster's item-drop chance. A group weight is not automatically the chance that a specific item drops per kill. An experience bonus does not necessarily increase currency or item rewards.

Ask precisely

When comparing a build or reporting a problem, include the class, skill, item name, map and what happened. “My damage is low” is difficult to diagnose; “this attack misses these monsters after changing this weapon” identifies something testable.
