invader drops are random you could hit 10 longobards and get no indicolite or you could hit just one longobard and get loads, The thing to remember about uber invaders is they carry material and gems from 4 different invaders as well as the special gems that only umber's drop, so the chances are slim of getting a specific piece of material or gem, When I attack umber's I am trying to get material and any special gems they drop are a bonus you could waste 1000's and hero energy attacking umber's for a pacific gem of material so it's best to hit the umber that you need lots of different material from obviously if you have all the material you need you will just have to hope you get luckie and the umber drops the gem that you want but with all the different types of material you need for shamans equipment it is unlikely that there will be no material you still need. I have lots of material from umber's that I did not want but now that I am making shaman equipment I am very happy to have it.

I hear ya. It's really nice when you're crafting shaman equipment and you happen to have all the materials needed just from random Ubers. Shame about the gems though. It would be much nicer, since that is the ONLY way to get those gems, if we were guaranteed at least one from each Uber slain. C'est la vie, I guess.
