It just doesn't work for me man...it doesn't feel right to go afk for 1-2 minutes everytime your enemies turn starts, in OS2 the scarecrow battle took me 15-20 minutes , like that's just garbage...there's enough dialogue ,reading and lore and books to read and things to do and experiment...the last damn thing i need is more time spent on boring combat mechanics.
It is called "Side Initiative". It is a variant of the initiative on page 270 of the DMG.
