Recently got the Dreadstone Summoner's Orb on Phinigel and have yet to see it proc a minion. I even tried with my bard in group and using Fierce Eye for the proc mod and not 1 pet proc. I will hopefully be getting the eye of fear tomorrow to upgrade to the Possessed version and will also test out that version with Sympathetic Minion 5.
Bump - Got an Eye of Fear tonight on raid and the Possessed Dreadstone Summoner's Orb is broken too. The Sympathetic Minion 5 proc does not seem to be working.. Feels like this would be easy to reproduce, not sure about fixing though.
https://forums.daybreakgames.com/eq/index.php?threads/live-update-bugs-02-21-18.247343/page-13 I brought this up a long, long time ago in the bug forum and supposedly it was fixed. But I never validated that because I simply ended up not using the weapon anymore since it wouldn't work. @Ngreth Thergn
the raid version wasn't fixed with the last patch (I missed the mention of it) but it is fixed (internally) for this upcoming patch.
