Here's a rule I've designed for disarming. What do you think?

This system is based on the princip that it's harder to disarm ar opponent when
he's a better fighting man than you, and is not based on what armor type he's 
wearing. 

===============================================================================

			     Disarming an opponent
			     ---------------------

In order to disarm an opponent, the attacker must make a successful attack vs. 
DAC (DAC=DisarmArmorClass).

DAC = 	 baseTHAC0
	-19("disarm-factor")
	-(to-hit-bonus for strenght and specialisation)
	-(penalty for non-proficency)
	-(AC-bonus for dexterity)
	-(magical bonuses on defender's armor (not counting shield)
	-1(if defender's weapon has a basket hilt)
 

The "disarm-factor" is decided like this:
	Joe Average is fighting his cousin Bill Average. They both have Average
	ability scores (8-12). Joe decides to disarm Bill. They are both 1st 
	level fighters using long swords, in which they are proficent. The 
	question is: What number need Joe to roll to disarm Bill? This number 
	is the "disarm-factor". In my ruling, this number is 19, and this 
	_includes_ the -4 penalty for called shot to arm. So, Joe tells the DM 
	that he will disarm Bill. He rolls a 17. He hits the hilt of Bill's 
	sword, but not good enough to disarm him.
	The DM may modify this factor as he likes.


Any disarm attempt causes no damage, as the blow is directed against the weapon
and not the man behind it. A disarm MUST be declared in advance, before initiative is rolled, or the attack is concidered a normal attack.

Example:Dr Izt Igot Euf, an 8th level ranger armed with a long sword +3 and a 
	strenght of 18(64) (+2/+3), decides to try to disarm Timok Swordhawk, 
	an 8th level fighter with long sword +3, strenght of 18(76) (+2/+4), 
	dex of 16 and double-specialist in longsword (+3/+3).

	Dr Izt's modified THAC0 is: 13(base)-3(magic)-2(strenght)=8
	
	Timok's DAC is: 13(baseTHAC0)-19-(2+3)(strenght and specialisation)
	-2(AC bonus for dex)=-13

	ie. the ranger must hit AC-13 to disarm the fighter.
