There are a substantial amount of mementos and sub-equipment in In Celebration of Violence. However, there is no in-game description of what these items actually do, leaving it up to the player to determine such things. Even the sub-equipment, which is often actively used, isn't always obvious in what the equipment does. This can be immensely frustrating, as many times you'll find a set of memento crystals (where you can purchase one of the 2-4 artifacts for 25-100 exp) but don't know what you'll be getting. This guide is an attempt to help alleviate those issues and help players find out just what these items are doing for them so they can make informed decisions on how to spend their exp.

Improves hidden “cleave” stat. “All weapons have a hidden cleave stat that adjusts the damage and power falloff after each enemy hit. For example, blunt weapons deal significantly less damage after passing through the first enemy while axes can effectively cleave through multiple enemies. Half a Shield improves the cleave stat and can even cause some attacks to increase in damage and power after hitting an enemy.” (Julian Edison)
