I started running monoliths with my Shaman today. One Echo type is the one where you have to cleanse an altar (?) that’ll continuously spawn monsters. What I noticed was that if I cleared the area around it before engaging it and pre-casted totems, they wouldn’t aggro monsters till I resummoned them.
I also noticed that totems will not attack the Training Dummy even if I cast a spell on it myself. I don’t know if these things have to do with each other, but I am just mentioning it in case it does. In general it’d be nice if totems would auto-target the Training Dummy since minions seem to ignore it too. Maybe in the form of a taunt skill that is cast on targets within the circle? I’m sure we can come up with a good solution.
EDIT: I can confirm that totems behave the same for any enemy that emerges after the totem has been set.
