This was my experience, too. It's affect/relationship with any other rule or situation never even came to mind.(un)reason said:We were always using a hodgepodge of basic and advanced D&D stuff, so we stuck with the BD&D 10 second rounds.
It was always 1 round = 1 minute for me, and even back then I thought that was way too long. 1 round = 6 seconds makes a lot more sense to me.We used 1 round = 1 minute, mainly because spell durations were predicated on that. It never sat very well, and I for one was very happy to see 3E reduce round length to 6 seconds.
