Great, thank you very much.
I have another question: Haven't upgraded anything so far, because I don't quite get it.
I can upgrade normal weapons with Titanite shards/chunks, right? But what do I do with Large Ember for example? I gave it to the Blacksmith in Undead Parish, near Darkroot Garden. What can I do now? Do I first have to upgrade a standard weapon in order to ascend it? And what do I need to do to upgrade a weapon with boss souls, and is it worth it?
