I did like a… 3 stamina to 1 heart ratio or something? Tried not to rush hearts so the game wouldn’t become a cake walk. In BotW I think I only added 3 hearts before maxing stamina all the way but there’s a lot harder content early on in TotK for me (it’s either boss variety or possibly because I’m expanding out way quicker because I know the map). So for TotK it was a ratio. I’m at max stamina now but I have like 8-9 hearts I think.
