Once the ember is in your inventory, you need to give it to Blacksmith Andre. There is a chest that contains the ember near the first butcher you encounter. To obtain this ember, you need to venture to the kitchen in the Depths. The reason for this is that I hadn’t given the Large Ember to Andre yet. When I upgraded my first weapon to +5, I found that the game wouldn’t let me upgrade to +6.
Upgrading your weapon to +6 requires a couple more steps than it took to get to +5, but it’s a pretty simple process. Once your weapon is sitting at +5, move on to the next step. Fortunately, these shards are really easy to obtain. The easiest way to get to that location is to take the elevator shortcut from the Firelink Shrine to the church. My favorite way to farm them is to kill the Balder Knights in the church close by Blacksmith Andre. You may not want to spare any souls for purchasing the shards just yet, and if so you can farm the shards instead. Of course all of the blacksmiths sell Titanite Shards, but Andre is the first one you’ll encounter. The easiest way to get these shards is to buy them from Blacksmith Andre for 800 souls each. In order to do this, you’ll need a total of 9 Titanite Shards. After you have chosen which weapon you’d like to create, you need to upgrade it to the +5 level.
