The drake sword, for those unfamiliar with it, is a sword that does 200 damage that you can get really early. It's a really bad design decision because it makes every other early game weapon about as appealing as a wet sock. I see players using it into their fifties. Who wants to use the same sword for fifty levels? Does it remain the best weapon hands down even past fifty when upgraded with dragon scales? I sure hope not. I quit using it now at level 28, have a *** sword upgraded to +6 that does better damage but of course it's slower and doesn't raise my magic resistance like the drake so it's still an inferior weapon to the drake sword at this point. I think it might finally be a better weapon by the time I get it up to +10
Why bother with any other weapon in the early game? The drake is also a pretty limited weapon in terms of versatility, as in it doesn't really have many combat moves, just the special strong attacks that eat it's durability, that's going to leave a lot of players untrained in how too use the more advanced combat techniques you get with other swords.
