I did like 3 hearts to every 1 stamina upgrade early, but I'm pretty bad at combat and needed the health increase. Once I was never really dying anymore, I maxed out stamina.
But why do the prayer statues still have a stamina wheel upgrade as an option? I got another four orbs today and went to trade in expecting it to just list heart container, but stamina wheel is still listed as an option even though it's not. Game is teasing me or something.
To be honest, though, I don't think I need any more stamina at this point.
I beat my first Lynel and it was ****ing ugly, but I didn't die. Hinox I have zero problems with anymore.
