WM/GS are absolutely *not* safe.

Basically - only damage that occurs on the boss turn are safe. Any damage that occurs on your turn will trigger it. CA damage will trigger it.

TBH I'm not even convinced that poison/HP burn are safe. I think it is really only damage that happens specifically when the boss attacks are safe. 

I'm with kram, I would have guessed a ctrlC ctrlV from golem but I'm not sure on anything not triggering outside of geos passive.

Wm/gs and brimstone 100% trigger it.  Clearly any damage from regular attacks. 

Poison and hp burn... idk tbh, but definitely seems like they trigger it...

Haven't had a chance to experiment a lot with it given that it costs energy, but my impression is that burn damage can trigger it, while the Geomancer passive does not, or at least I feel like I've passed the thresholds without triggering it when that has been my only real source of damage.

Thank you.  Basically sounds like one more thing I can't do having not been lucky enough to pull 1 Geo out of hundreds of epic pulls.  I've been trying to find a substitute, but it looks like I need a whole new set of toons to focus on heavy resists.

I wish Plarium's right hand knew what its left hand was doing... I'm not sure why Plarium makes Geo essential but cries "cheater" when someone uses Paragon. 

Do you have 3 painkeepers? 

Will do the 3 painkeeper comp when I get a third

I've been told nothing avoids it, using twn's turn based damage is just to control WHEN RT procs
