I would love to have info on the Umbracrux for Rogue:
How does the totem effect other players in a group? Does it take away from their skills? My group is saying that it forces them to hit the totem…is this correct?
What exactly does 20% effectiveness mean? Please…any information on this would be appreciated.
Other players should love when you put a totem down. My clan gets mad when I forget, in fact.
It makes everyone’s damage much stronger for bosses and elite packs. It does not force them to hit it unless you want to and really, they should if enemies are close.
If you have target lock persist on, it may target it and ignore other enemies.
Thank you so much! 
I actually don’t use Umbracrux in group. I prefer Doombringer or another legendary dagger. While Umbracrux is great for bosses, it’s less effective for clearing mobs.
I always have some totem fun while waiting at the worldboss spawn. If theres a class with active minions waiting i throw the totem near them 
I’m still finding it hard to see the benefit of Umbracrux. I finally got one, and it’s almost perfect!. No GAs but that’s ok for now. I do have a doom bringer, surely that’s better, no?. But all builds lately seem tied to Umbra. I get its design means aoe potential but with it moving every time I do my now one and only poison trap, explain to me please. Thanks.
