Whats your opinion on elven curved blades?
They seem to be more of a RP choice. And only really work in a few builds. That being said I still haven't gotten to Chapter 3 so I don't know what the itemization is like later on. With how much Haplo praises the Serpent Prince I get the sense that some weapons just have end game stats that are superior to others.
Curveblade is like a finesseable Fauchard without reach. Elves get it with Martial. I'd try it on an elf EK.
It's awkward to get all you want out of both finesse and two-handing. There are some nice ones (one nice one?) late. Even weirder than Curveblade is the two-bladed agile, keen force sword. Anyone figured out what to do with that?
Serpent Prince isn't really a top damaging weapon in the game. BUT if you're lucky, you can get it in Act 3. Even late Act 2 if very lucky. For when you get it, its extremly good. And offers the safety of reach.
Otherwise fauchards are one of the top weapon categories, yeah - but the best one from artisan, Mastery, is a pretty special weapon, focused on Combat Maneuver users - awesome for them, barely so-so for others.
Greataxes are always good (or best) for damage. Bastard swords (large) are good if you use size modifiers. Curved Blades are actually among best two-handers. And, importantly, the best one can be gotten early - right after Act 3. Its a bit of a hidden/secret weapon, though. Also there's another good one from artisan, that has ghost touch - very handy.
Note noone is forcing you to finesse ECBs. That you can doesn't mean you should.
