Research points can also be gained by consuming Knowledge Fragments or Mana Beans and incurring the Warp event, "Strange whispers reveal secrets to you," though these methods are unreliable in frequency and specificity, and are potentially harmful to the player.

When scanning Aura Nodes the number of points gained is roughly 1/10th of each aspect in the node. If a new aspect is discovered via scanning, the player will gain 2 extra points than normal.

Because of the way that aspects are sorted, Compound aspects cannot be scanned until their constitutive aspects are known if an item or block cannot be scanned in this event, a tooltip will appear on the lower-right corner of the screen informing the player in a roundabout way about a certain aspect that they need to know of before the item can be scanned. There are 2 main methods of acquiring points: scanning objects with a Thaumometer, or combining two aspects at a Research Table into their compound aspect.
