has this been in the whole time? i don't remember it from my first few golem kills, and i don't think i've seen a fright die since he started doing it. i don't remember noticing on the change log that it had been added. http://archive.is/rtnRx there's a post here from 2004 suggesting its a new thing.
Yup. He had it on AK, and he's always had it here. Nester fearplane cut.txt 32294 [Sun Jun 10 19:59:50 2012] Stairs has been Magi cursed. Actually I think spin stuns aren't lasting as long as they should be on TAKP.
Oh, the reason why you didn't notice it during the first couple of weeks after we launched fearplane is because there was a code issue that was preventing the procs from triggering if the target already had the debuff/DoT on. That was totally gimping Dread's AoE and Fright's proc.
