You also incur an attack of opportunity. Improved disarm eliminates the attack of opportunity and drops to the penalty to -4.Specifics: The character can attempt to disarm an opponent in melee combat. Attempting a disarm applies a -6 penalty to the character's attack roll, and the combatant with the larger weapon gains a +4 bonus per size category of difference. A successful hit deals normal damage, and if the opponent fails a discipline check then the weapon flies from the opponent's hands.
Now the problem as I see it is the size category issue. There are 4 categories. Tiny, small, medium and large. That means and each shift is +4. That means that a Large Weapon attacking a Tiny weapon gets +12 to their attack……
That nets you a +6 to your attack. +8 if you take improved disarm and no risk of Attack of Opportunity. For small weapons it is a +2 or +4.
My question is, why wouldn’t someone with a large weapon not spam disarm on all small and tiny weapons. Keep in mind that small races pretty much exclusively use small and tiny weapons. In addition, remember that the server already has big benefits for large weapons, including +2 AB and 1.5X damage and as a result, 2 hand large weapons are the norm. To add more weight to this, a number of small weapons have been moved to tiny on this server.
Now add on top of all of this the immersion problem. I don’t understand why I should be more likely to hit a character with my greatsword if I am aiming directly for his dagger. If anything I should be less likely. I get that they wanted to increase the likelihood of the disarm check being successful as the larger weight provides more force to knock a weapon away. However, it really just seems like lazy coding to increase the AB. Then they just need one number for attack to hit and the discipline check, when there are two dynamics at play. First, you should be less likely to hit a dagger if you are trying to hit it with a greatsword. Then you should be more likely to knock it away. Large weapons aren't designed for precision moves like hitting a dagger. They are designed for caving in a skull, or shoulder, or hip, or whatever you manage to get.
All in all, this just seems like a crazy way to benefit large weapons that is built into the software, when large weapons are already dominant on the server due to their other benefits. Am I reading this wrong or are my concerns misplaced?
