i've only been playing for a few months and have a GM Sorcerer, a Magus Theurgist and a journeyman Necromancer. Throughout my travels, the only time i noticed a change is during holidays, and all that changes is new items in the shopping district. How about every month we have 2 days that dont need something special to happen for these to occur. One day could be Fizzle free day, and another day could be unlimited mana day. so twice a month we could have just a little more fun :D
:) :-) :D
