[Wids]

Good point. Even aside from the usual undead, elementals and oozes, there are those random creatures which are randomly gifted with immunity to Critical Hits and Sneak Attacks. I wouldn't say that most creatures on the entire server have that immunity, but the percentage does vary by location (which is why characters who depend on Crits and/or Sneak Attacks do well to avoid crypts, where the amount of creatures with that immunity is pretty close to 100%).

But still, I find the dagger appealing for its light weight, small footprint and decent Critical Threat range, even if its damage isn't very good. Light weight = less encumbrance, which means more capacity for loot and/or better odds of escape if something damages your Strength. But it would be nice if we could also throw the daggers, like characters in tabletop D&D can. The most successful player-character in my online D&D campaign is a Rogue (soon to be Rogue/Assassin), whose only weapons are a shortbow and 17 daggers. He hasn't had to use the shortbow yet, and yet he's already racked up quite a body count, despite only wielding daggers.
