This is the Channeler neck from Grendish X4 - http://u.eq2wire.com/item/index/2637520025 In the description it says: Changes Sanctuary of Darkness into a short range group spell. It will also grant 20% damage reduction to magical attacks. It does apply the buff visibly on group members. However, they do not seem the receive the benefits of the buff. I tested it in combat and out and the run speed component was seen on the Channeler, but was not seen on the grouped allies. I do not know if the control effects or damage reduction are similarly not working. Thanks for taking a look.
Thanks for reporting it. It looks like everything except the run speed is working properly, but just to make sure we've made some backend changes to the effect to improve reliability. Coming to live servers near you soon.
