Before the recent tests it was only able to cut the time needed to learn by 49%. Lately, there has been some oddity in it...
I tried to reduce a 2-day skill to 1 day, donated to all 3 giants (2000 favor x 3), but at the 3rd giant, and with 1 day and 14 hours left, it said that I was already learning as fast as I can.
Just wondering... how does it work now? Is it limited to a certain percentage or what? This is one part of the game that the mechanics I haven't really got to understand.
