I don't know if someone already wrote about this but today I was trying to understand why Will couldn't use "read thoughts", so I opened the character sheet of the party. While I was there I digged a bit on the four sheets, that's when I noticed that Shadowheart's tags gave away infos that to me felt like spoiler (not to me that already have completed the first act but to a new player who is discovering the companions' past through dialogues and exploration).
