ok now I realised that the bartender is also tier 4 - and you got the percentages right , she’s in the cage about every second purge.

The problem is we already have one and we’re dismissing the new ones immediately , so I didn’t count them in the purges , like Iskar … I only counted the “normal” t4 thralls and we’ve been pretty unlucky there

but for thralls tier 1 purge is useless , the most interesting ones can be gotten in tier 5 - mainly various archers like Dennu etc who have high vitality bonus and can have 7-9k HP
