Fye's application of entangled seems to just not work. It says entangled on the screen but damage isn't reduced.
I also wanted to request a way to see what the effects of a companion will be once you end your turn, I like Fye and other companions that debuff enemies as a safety net but it's a bit hard to plan around just doing the math in my head. Also at level 8 Beryl's sprite almost entirely cover's Fye's clickable area so it's hard to mouse over it for the tooltip.
As an aside, I expected not to have any interest in Ruby but she may be my favorite character story.
