Not sure everyone is aware but Google also has a rewards app where you answer some simple questions (normally 30seconds) and they give you some free credit too spend in the playstore. The amount I made this week was around £1.60 and that covers this phantom king pack.

TG is 180 capped :) Lots of those and I have couple of champions, paladins, succubus above level 160.
The dwarf series by Markus Heitz. Read it in German but it also has been translated. First book https://www.amazon.com/Dwarves-Markus-Heitz/dp/0316049441/ there are actually five. The last one has not been translated yet, but it lost some quality. Read it after surgery in hospital, even while hospitals are boring as shit the fifth book didn't help too much :)
I'll suggest Discord again (however I have no idea how it works on mobile and on background). It's all free however and don't require paid servers like TS. (TS is song of the past, with all those free apps of decent quality, especially for using twice a month).

We can try and check different ones. (I'm not lobbying for my idea, just giving an alternative ;)
