I worked on the magic accuracy magian staff for the sole purpose of having the listed -12% recast reduction, only to find that it isn't actually -12%. I have Yama's Staff +2, not sure on the final trial number, but the trial number just before it is 2214 for Yama's Staff +1.
Klimaform's default recast is 3:00 or 180 seconds. With Yama's Staff +2, it is reduced to 2:51 or 171 seconds. That's only a -5% reduction, not the advertised -12%. It should have been about 2:38 or 158 seconds if the description was accurate.
This is all completely irrelevant, but I know you're going to ask it anyway:
