Proguide knowledge tips
In this tutorial you can find a series of suggestion to considerably reduce the time needed to develop a Knowledge. To develop a knowledge that takes a very long time to be upgraded, I suggest you to take some precautions.
For example, a few weeks ago I upgraded the knowledge "Number of Marches II". At first, I had only Hero's skill "knowledge speed" at level 10 and the knowledge took almost an year.
Then, I understood that I could take advantage from some boosts and objects:
In the "Development" section of the "Boosts" you can find "knowledge upgrade speed up 35%"
You can equip your Hero and Shaman with special equipment. I equipped my Hero with 2 "Falcon Figurines" at legendary class; each of them increase learning speed by 30%
Pay attention to the current events. I developed the knowledge when the event "knowledge upgrades speed up by 10%" was ongoing.
Well, at least the time to develop this knowledge has been 16w6d, so a considerable reduction!
