Okay, so I got to talk to Deck, & all he said about Confusion was...
"[20:18:24] Deck_Knight Confusion's counter lowers at each check, so if you roll 2 confusion actions, it lowers at the first check."
After searching some sources, Confusion actually lasts 2-5 actions in-game, with the check happening each time the "(x) is confused!" message shows up, which means it effectively lasts 1-4 actions, & since ASB apparently follows in-game on checks, confusion apparently always lasts one actions less than advertised... >_>
All I have to say on the thing we were arguing about is w/e, but yeah. Confusion is dumb.
