From the looks of it in the research tree (nowhere near ch.19 personally) it looks like a new profile portrait photo. Usually other chapters the last research is new ancient wonders though... maybe there is a surprise along with the photo? Someone further advanced than me should be able to answer this when they get on next.The last research in chapter 19,,,,,, Does anyone know what 'ULTIMATE POWER' means??? Is it an upgrade for ones troops??,,, A combat structure???,,, Wishful thinking???,,,,
Thank you,,@Zorlog you get it when selling your Lvl 4 Fortress or Revenge.
Have a read through the Ch19 thread which I see you also found.
OK,,, I sold my level 4 portal,,,,, Research shows that I now have 1 Ultimate Power medallion,,,, It does not,,, however,,,, show that I have completed the research,,, So what do I do now????,,, sell off everything else surrounding the Portal?? How do I get to chapter 20????
