Not only that, the filter for 'check all' doesn't work at all. I can set it to "uncommon or lower" and it always checks everything anyway.
Btw, don't offer or sell stuff directly. Amrita is easy to get, and you can make a lot more gold by breaking items down first. Or just save the materials, you're going to need them later. You can also upgrade materials to higher tiers.
Also, very important lesson learned from Cohh. Don't "sell" items going to "all items" and selecting the rarity, select all and sell. Unlike deconstruct which only selects armor and weapons, selling also sets all your consumables and materials. He sold all his items, and with a limit on 20 buybacks, he lost... alot.
My routine so far is looking at items, storing/locking things with abilities I might want to have, deconstructing all weapons/armor, then the only things I sell are accessories. I do that with every mission, sorting only by "level".
Just got to the first boat. Died twice to every boss except the lightning doggy which took me at least 10+ until I switched to low stance double swords continuously dodging until his lightning beam to the left and face hitting 3 times, then backing off. Rinse repeat, the fight took 15 minutes but only used one elixir at the end.
I think the difficulty spike, if there is one, from the Soulsborne games, comes from Nioh punishing greed and rushing to a much higher degree. That said, taking it too slow really trivializes some things. Mobs can follow you for a long distance if you keep next to them, or continuously hit them. However, if you aggro, run away a bit, they will break path and go back nearly always facing away from you. There are yokai encounters you can kill by walking up to cloud, trigger it, stand there until it aggros, run away, break follow, go back slowly and backstab, run away, rinse repeat.
So far my game to beat for GOTY. Not sure what else is coming this year that can beat it (possibly RDR 2 or LOU2 if they are released this year)
