In the Spriggan tree, the Huntersbane node converts your vines from melee to ranged and they get access to the nodes that affect Spirit Thorns. Also in the Spriggan tree, the Ancestral Call node gives Spirit Thorns rage and ward generation if you hit at least one enemy.
I want to understand how Ancestral Call affects Huntersbane, does it generate rage and ward for your vines? Or do your vines now generate rage and ward for you?
