Fucking hell rem this is one of the easier ones to beat too and it was still a colosall pain in the ass with multiple failures lol. that's 2 challenges done on a legit playthrough. doubt i'll go for the other ones tho since the benefits aren't all that.
Warrior build focusing on dexterity and agility. somehow got empress end too so that's neat. key here was publishing karryn's stats for extra income early on and getting offensive edicts before fighting the level boss. makes a world of difference.
