After give the heart to the sorcerer and pass all those dungeon new boss, I am kinda lost and doesnt know what should i do. Currently level 30 btw. Please helpppp

I'm at lvl 28, reached the first boss, can get it to 60% HP no issue, the problem is the regen HP part, it heals faster than I can hurt it, so most of the damage I've made heals back, I assume I'm too low leveled, what would the recommended level be for the bosses?...

I’m playing on the steam deck but can’t start the game as the keys/buttons aren’t configured. I somehow skipped the button layout tutorial so can’t remap the keys. Can devs or anyone else playing this send me the key map out so I can rebind the controls please...

How can I obtain the petrified sword? I have found the sword, but I cannot obtain it.

Is the dlc included?
