Iji sells Somber stones. The Claymore can't use 'em - but the big sword you got with the Weeping Penninsula Boss does. A +4 Grafted greatsword used two-handed is about the same as a Claymore +12 at a rough guess. Hitting L2 gives you +5 on every stat for a couple of minutes.
But you only need 1 each of +1 to +4 for an upgrade on Somber weapons.

Actually didn’t liked it on the tv after that, you don’t notice the ”grain” or “color smearing” of that graphic engine as much handheld as on tv.
