Refresh has finally been dewonked, and updated.
Most of you have been well aware of the power perception problems, where you PERCEIVEd when Refresh was up and got a value approximately 60 times what the value of the spell duration actually was. In going through the code, an artificial mana cap was also in place the spell, making it so you couldn't get any additional effect for more than thirty mana. This has been corrected.
Unfortunately, even with max mana, this spell only lasted 15 minutes. :/ So, Atrathien, Rhook, Brigdha, and I decided to go and uptweak the difficulty, to allow us to substantially uptweak the spell duration. I think you all will be pleasantly surprised, because this spell really does grow with your magical abilities now. :) We're going to be monitoring it over the next couple of days to make sure it's not too powerful, but I feel safe in saying that you all will see it as a massive improvement.
Sincerely,
Nionon
