So, I've just reached Chapter 4 in The Witcher (playing the Enhanced Edition if that matters), with a melee-focused build for Geralt, and I'm getting to the point where my options for weapons really open up.
Specifically, I now have enough Red and Blue Meteorite pieces to put together just about any combination of those two, along with one Yellow Meteorite, and my current steel sword is Harvall, and I have an Illegal Sword in the bank. The Blacksmiths son in Murky Waters is offering Gwalhir for sale as well. (I can easily afford it if I go that route.)
For Silver, I used my first three runes to make a Rune Sword, with 2 Earth and one Sun rune. I now have several of all three runes.
What Rune and Meteorite combinations are going to offer me the most effective blades for upcoming encounters, or is there some other sword I should be chasing while ignoring Runes/Meteorites? (Alternately, is it possible to use the Meteorite pieces to enhance an existing sword like Harvall? Because that would be incredible.)
