That's what Miyazaki said when asked about it.Is it confirmed? I thought you could only use it for finishing off the bosses.
Well there's a finite number of skills you can get and some are locked before you find them in the world/get them from bosses. It's not as big of a growth as just grinding levels.Really? I thought you spend the resource you gain from killing enemies (souls, echoes, whatever) to unlock stuff in the skill trees? In which case grinding would be possible.
