A technology gives the player new features or abilities in Dungeon Overlord.

Helper Goblin says: "Technology is the second part of your quest of expansion and conquest. Without the right technologies, my lord, we will be stunted in our growth and more knowledgeable overlords may come and terrorize us! Put your warlocks to use and let us hasten to learn what there is to be learned my lord!"

Below you will find a table (that is sortable) of all of the technologies that players may research. Warlocks are the game's primary means of researching technologies and each Warlock requires four Library Tiles in order to have enough space to ponder, meditate, and understand the meaning of their world efficiently, at least if he is not shocked. Since Research is so important, many players have a large number of Warlocks within their dungeons.

Liches can also function as a Research helper, assisting the Warlock but would not be feasible for lower level players.
