Research

Research is the basic currency for purchasing technologies. Players earn it with warlocks at a library. It drops and stacks on library tiles that don't have furniture.

Current research available to be spent on technologies is displayed under the experience bar next to the book icon. Mousing over the book icon displays research rate in the current dungeon being viewed. Research accumulates at 18 research per Warlock per hour multiplied by any research modifiers. You can see the items and upgrades that provide research modifiers in the library article.

In order to calculate an optimal number of the research-increase and stack-increase furniture for your Library, you can use. Be sure to thank him in the thread if his tool helped you out, as the calcuations are migraine-inducing without some sort of template.
