Book of darkness · Old School RuneScape: Equipment requirements

Using this reference

For Book of darkness, check the requirements against your current character before comparing bonuses. A requirement tells you whether a recorded condition is met; it does not measure the benefit of equipping the item. Enter your own values in the checker to see the remaining gap for each stat.

Keep requirements and performance separate when comparing alternatives. Two items can be equally accessible but behave differently in a build. The reference does not automatically apply temporary bonuses, class restrictions or special handling rules that are not present in its source fields.
