As stated in the title, indirectly casting Thornshield using the Hazelroot unique scepter does not trigger the related skill “Barbed Thicket” which does not specify that Thornshield must be directly cast to be activated.
I hope this is a bug and not an oversight on skill wording, as this would promote a lot of cross-skill synergy with werebear’s ability to spawn vines through Fury Leap.
Thanks!
