Drops worth chasing
Mostly for the kill count, pets and combat achievements.
“90% chance by” is how many kills (or chests) give a 90% chance of having the drop; most players get it sooner, and some much later. Raid rates are a share of unique drops, which depend on points and team size. See every upgrade in order on the Ironman gear progression page.
