This is a new system that allows big creatures to do more damage by putting their weight behind the attack...with potential drawbacks. It is deadly when using very large creatures and would probably be best used in a realistic campaign.

Thrown Weight
By Roger Bacon (rogerbacon@adelphia.net)
(based on a system used in RoleMasterä)
Force = mass times velocity, as we were all taught back in high school. In standard d20 rules mass has no effect on damage. Thrown Weight is an optional rule to allow the mass of an attacker, character or monster, to have an effect. Anyone can use the thrown weight rules, but those who take the “Thrown Weight” feat will use their weight better (just like anyone can attempt to disarm but those with the feat will do so better).
Feat: Throw Weight
Prerequisites: Power Attack, Base Attack Bonus +1 or greater, minimum weight 200 pounds
Benefit: Characters with this feat only get –2/-4 for using 50% or 100% of their thrown weight bonus on damage.
Thrown weight can only be used as part of a normal or full-round melee attack. It cannot be used in grappling, ranged attacks, disarm attacks, trips, or on attacks of opportunity.
Normal: Normally the penalty for using thrown weight is –4/-8 to one’s armor class.
Thrown Weight procedure: A character may decide to use either 50% or 100% of his thrown weight bonus as a modifier to a damage roll by taking a –4 or –8 to his armor class until his next action. If the character fails to hit his target he must make a dex roll (DC 10 for using 50% thrown weight or DC 15 for using 100% of his thrown weight). Creatures with more than two legs add +4 to this roll. If the character fails this roll he falls prone and losses any subsequent attacks for his turn. When he falls prone he triggers an attack of opportunity from anyone whose threatened area he is in. A moving character, including a charging one, continues moving for ½ of the distance he moved prior to his attack roll, not to exceed his maximum distance movable per turn, and triggering attacks of opportunity as normal for movement before falling prone.. He may also not make attacks of opportunity while prone.
A character may decide to use thrown weight before each attack roll is rolled. If he uses the thrown weight for even one attack, though, he suffers the penalty to armor class until his next turn.
The bonus a character gets to damage by using thrown weight is based on his weight:
Weight (in pounds) Bonus to damage
200 +2
300 +4
400 +6
500 +8
600 +10
700 +12
800 +14
900 +16
1000 +18
1200 +20
1400 +22
1600 +24
1800 +26
2000 +28
2500 +30
+500 +2 extra
To calculate a character’s weight in pounds use the following formula.
Height^3 * 0.0000107 * 47, where Height is height in inches.
The 47 in the above formula is the average weight of a cubic foot of flesh, bone, and other parts found in humans. For creatures made out of different materials, such as golems, replace the 47 with other numbers such as:
Bone = 115
Brass 550
Clay = 140
Gold = 1,205
Granite = 170
Iron = 445
Ivory = 117
Ice = 57.2
Leather = 54
Platinum = 1340
Silver = 655
Wax = 112
Wood (cedar) = 28
Wood (pine) = 28
Wood (ash) = 47
Wood (Balsa) = 8
The above formula is accurate for generally humanoid-shaped creatures. For creatures who are longer than they are tall, use length.
For creatures who are denser than normal, assign a density variable and multiply weight by that number. Values for some of the standard races are given below.
Halflings: x1.5
Dwarves: x1.77
Orcs: x1.3
Elves: x0.75
