There is no "best" armor or weapon in the game, it's not like some standard JRPG, or action RPG where there is a "best" armor and weapon. In the Souls games it all comes down to your build, and how well you like the move-set of a weapon, rather than how powerful it is. --- "..."
Allone Captain Armor is beastly at +10.. It's like the Black Knight Armor of this game.. --- PSN: GoTigers9999 Nintendo ID: Iori9999 3DS Friend Code: 4012-3366-0941 Steam ID: Izayoi9999 Stream URL: http://www.twitch.tv/iori9999
Rapier +10 for dex, great sword +10 for str. Imported tunic for both. But that's just my humble opinion. I'd agree with everyone else though it completely depends on your build and taste. As the movesets vary. --- This is your fault. I'm going to kill you. And all the cake is gone. You don't even care, do you?
