Wut ? It's the same as in the souls series.

And in the final game, you will get a shop to use your money.

Not really. Weapon degradation in Demon's and Dark Souls worked similar, but after Dark Souls 2, all weapons start degradating when you use it but replenish themselves everytime you use a bonfire, which is not the case on Ni-Oh (You have to use a wetstone or your weapon will break, no matter how many times you use the shrine).

Oh, i didn't remember it, because the last souls i did was bloodborne, and your weapons didn't auto-repair themselves.

That being said, your weapons in Bloodborne took forever to get damaged, and you could fix them quickly with a fast visit to the Hunter's Dream. Which doesn't look like a similar scenario in Ni-Oh.

please if you apply there, tell them they shouldnt make this game too grindy.

They have a mission interface, i am worried they will force you to play multiple missions in order to preogress

I got the platinum on that demo lol. Killed Nue (Thunder Boss) and started my journey to find every single Kodama. By May 5th I was a level 45 tank.

So I started matchmaking with lower levels and helped 4 or 5 players completing the first area.

Strength 20 - Main weapon Axe in high stance. Do or die XD.
Heart 20 - Lots of combos and exchanges.
Stamina 20 - I was able to equip and carry anything at that point. My defense was amazing.

But now I wonder what could have happened if I decided to main swords or spears, or even a magical build.

Prior to this, PT was my favorite demo. But Ni Oh surpassed it. I can't wait to play the full release now.
