Re: Why superior crystal swords?
I'm partial to ethereal crystal swords for runewords that don't involve hitting the enemy, simply because I like the look. I might by accident hit a monster every once in a while, but I've never had one break on me.
For characters that don't get hit a lot, ethereal Spirit in a Monarch will save you 10 strength points if it's your heaviest item. I used one on my lightning sorc for months without it breaking.
