Actually, Drizzt was used as an example of how all
drow dual wield. He learned to dual wield as a fighter, not a ranger. Also, in 2e any warrior or rogue with an 17 or 18 dex can dual wield with a small weapon in his off hand with only modest penalties. He needn't be a ranger or even have extra proficiencies. Any warrior or rogue with a dexterity of 15 or less gets -2,-4. If his dexterity is 16 the penalty is -1,-3. For 17 or 18 dex the penalty is -0,-2. 19 or 20 dex means -0, -1. 21 dex or higher means free dual wielding with no penalties.
So, why could Drizzt dual wield? His dex was 20. He could do it for free with almost no penalties anyway. (Whether in light armor or not!)
Why could he wield 2 large weapons with no penalties? Because he was Drow. (In 2e all drow could dual wield with 2 large weapons for free)
What the hell did Drizzt get out of being a Ranger anyway in 2e? Charm animal. And that -1 penalty he got in his off hand was negated if he wore studded leather or lighter. But didn't he always wear chain mail?
For my source.........page 96 of my 2e players handbook. (The section entitled Attacking with Two Weapons)
page 14 of the same book. (Table 2)
Bottom line: NIGHTMARE was right on this one. (But I have to agree he kind of pulled the Aragorn thing out his ass.
