Legendary Deeds

Introduced in the Guardians Expansion, Legendary Deeds are special objectives that offer rewards to the Empire that completes them. These rewards can be large sums of Resources, unique Technologies, special Items, or one of the Legendary Buildings. However, each of these Legendary Deeds can be completed by only one Empire in the world, and as such only one Empire can reap the rewards from completing them.

Every Research Era except Era VI has three Legendary Deeds that are available to be completed by all the Empires in the game. The Legendary Deeds available in the later Eras are unlocked for all Empires to complete once any Empire reaches that Era, regardless of their own technological progress; so an Empire that is still in Era II may complete a Deed in Era IV, so long as another Empire somewhere in the world has reached Era IV.

Legendary Deeds can be seen in the Research Screen (Hotkey F3) to the left of the technology pools for each era. Deeds that are available for completion will have full-color pictures, while those that are not yet available will be in grey scale. To the right of the image is a bar that will be black if the Deed has not been completed by any other Empire yet, and it will gradually fill up with white as you grow closer to completing the Deed. If an Empire has already completed the Deed, the bar will instead be the color of their Empire, with their faction icon in the center; if the Empire in question has not been met yet, it will instead be a question mark. You can learn more about each Legendary Deed - what must be done to complete it, what the reward is, and your rank towards completing it compared to every other Empire - by hovering over the Deed's picture. While the Legendary Building deeds for each Era are always the same, the ten other legendary Deeds will randomly have one of two possible objectives to complete, so it's worth taking note of the objectives with each game.
