There are two cards incomming that are reffering to highest or lowest STR.
Roseroad patrol
'... While you control a character whith the highest STR in play, Roseroad patrol gains stealth'
House Florent Knight
Forced Reaction: After House Florent Knight enters play, choose character with the lowest STR in play and discard it from play.
What happens if there is a tie for this specific condition i.e. There are two or more characters with highest/lowest STR?
