Let's do an experiment!
Post your Astrology skill, and how much each of the following actions gives you:
Astrology: 76
PREDICT WEATHER: 3/34
PERCEIVE KATAMBA: 0/34 ?
PERCEIVE XIBAR: 0/34 ?
PERCEIVE YAVASH: 0/34 ?
Conditions: Outdoors, Clear Sky, Sun up, Katamba up, Xibar down, Yavash down, no spell buffs.
In my experience, something has changed to the amount of EXP these actions give, and it happened in the last few months. It was my experience that perceiving a moon would give more EXP when the moon was down, or you were indoors, unable to see it--as if the act of focusing your senses through the planet or other obstacles was helping you learn more.
Has the timer on these actions changed any from ~5 minutes?
Could it be at all related to this? http://forums.play.net/forums/DragonRealms/Discussions%20with%20DragonRealms%20Staff%20and%20Players/Game%20Master%20and%20Official%20Announcements/view/1866 This was right around the time where I stopped paying attention to EXP gains on my old moon mage.
