Currently, there is a broken interaction with Spiked Totem and Thorn Totems.
I tested the ability to create poison clouds on with Thorn Totem on death or unsummon then took the Spiked Totem node in Spriggan form.
At this point, when I do cast the totems and they die or get unsummoned while in Spriggan form, they are not creating the poison cloud at all. When I transform back to human form, the thorn totems do work as normal.
