Useful information. Ty

Thanks for your post.

The more damage your hero takes off of the Uber, the better your chances for getting better rewards. Sustain attack as high as your knowledge allows and THEN use the enhanced attack. 

Materials, gems and boosters etc. all increase in quality as the damage raises.

And PLEASE do yourself a favor and do some research in the Invaders/hero skills areas before wasting your energy on them :)

Wise Jarls!

We have prepared a table for you. Use it to find out what gems and materials of different Invaders you can get when you attack Uber Invaders.

There is, the materials are possibly inferred, perhaps because they wouldnt fit neatly into the graphic.

If you know what the individual invaders drop , then you know, or can work out, what the Ubers drop.Atlernatively consult the other pertinent posts in Game Data.

As the ubers  drop  special gems, not available anywhere else, its not clear cut, so a table of them,is the most useful part.
