Blueprints allow you to copy and save large constructions of multiple structures. Blueprints are unlocked with Entropic Echo , the first Entropic Research earned by clearing the Entropy around the Great Portal .
The Blueprints menu can save your creations to seven tabs, themed after the six Elements and Entropy, in whatever arrangement you wish. Blueprints can also be exported and imported as strings to copy them across different games and between players. An unlimited number of Blueprints can be saved for each tab.
When you place a blueprint, it will appear in the world as faint blue Echoes. Placing the matching items from your inventory onto these echoes will place those structures with the correct orientation and settings for the blueprint. You can also quickly grab the corresponding item required for the echo using the Pipette tool (Q button) as long as it is available in your inventory.
Once you have the Echotracer spell, this spell will fill in Echoes automatically while it is active. A purple aura forms around you and items from your inventory will make their way towards the Echoes, filling them in. Echotracer might be slow and have small range at first, but a couple of upgrades will change that.
