No guys, you miseed the point
I meant, sticking to a roleplay style, a Bladesinger would not touch anything but his chosen weapon type. Now keeping character knowledge separate from player knowledge, there is no way a young elf, captured by some insane mage, would know that, two weeks down the road he'd be facing off against a Demilich.
All this elf knows is that he needs to escape and find out what's going on, but wants to be ready for anything. Now his trusty swords have never failed him before (BG1 rarely had something you couldn't hit with the Varscona, were there any...?) so why now? Does the warmer climate affect a baddies' immunity to weapon types?
Oh, and I find it hard to believe that Golems would be hurt by Blunt weapons only. You hit a clay golem with a stick, it probably won't hurt, but if you slice up the clay that makes it, you're bound to do some damage. Iron and Adamantite Golems would seem to be indestructible, and should be unable to be killed by sling bullets...
Anyways, I guess I get to quit roleplaying at least for a couple of battles, I think I'll put 1 point in Mace and 1 point in Flail/Warhammer for the Flail of Ages/Crom Faeyr.
