Either we need clarification on what counts as what or the tooltips need a lot more clarity in their wording.
The beastmaster tree has the partner and comfort nodes which only work if you control exactly one minion. As expected, these do not work if you have a companion and then drop a totem.
The druid tree has Natural Duality and Strengthened Bond which say they work if you control exactly one companion. These nodes work when I have just my spriggan out, but when I add totems they no longer work. Totems are not companions, so either that node needs to read minion or there’s a bug.
